During their two seasons on the ice, Dr. Mellish and her team successfully collected data from forty Weddell seals. Back in their labs in Alaska, Colorado, and Oregon, the researchers began processing their data. The first step was to make sense of it all! Knowledge of computer programming helped Dr. Hindle sort through the data. She began by looking at the relationships between variables. She used those relationships to build mathematical models that answered the team's research questions. At the same time, Dr. Mellish was working to analyze the team's collection of thermal images. Upon close analysis, patterns began to appear. Dr. Mellish determined that while all the seals sampled lost heat from the same areas of their body, the leaner seals (the juveniles and adult females who'd recently weaned pups) tended to lose more heat than the fatter seals. This finding supports the team's hypothesis that leaner seals may be less able to adapt to changing conditons than seals with more stored blubber. While complete models will take years to build, initial modeling results show that Weddell seals live in a careful balance with their polar environment. The data indicates that if ice conditions continue to change, this balance could be thrown off. While scientists are still uncertain what the effects of climate change will be on the polar regions, they are increasingly certain that there will be effects. Research projects like this one are important because they increase scientists' ability to predict how animals and ecosystems may respond to such changes.         WHO IS STUDYING SEALS?   DATA (n) - values of something measured   PROCESS (v) - to sort and analyze recorded data   VARIABLE (n) - an element of a system that can change   MODEL (n) - in science, a representation of data that makes something easier to quantify, predict or understand   ANALYZE (v) - to carefully examine something

Many are sedentary, sensitive to change, and easy to access for study. Scientists are usually more able to discover the source of change in this kind of habitat. Once those sources are found, they can identify and compare changes that are natural from those that are man-made. Click the image below to discover the different zones of the nearshore ecosystem. The Nearshore Ecosystems team collects data in the tidal areas. Researchers are focused on learning about the variety and abundance of the species living at sites in Prince William Sound, the outer Kenai Peninsula, and Lower Cook Inlet. This data will help scientists find answers for questions like: • Is the nearshore environment changing significantly from year to year? • Have resources in this environment recovered from the 1989 oil spill? If not, are there reasons other than the oil spill? • Are changes in offshore conditions also causing changes in the nearshore habitats? This project focuses on organisms that are considered crucial to the nearshore ecosystem’s health. One such key species is the black oystercatcher. These shorebirds are good candidates for monitoring projects because they have a long lifespan. Over that lifetime, the oystercatcher lives in and depends upon intertidal habitats. This is where they mate, nest, and raise their young. Even though black oystercatchers aren’t benthic animals, they eat a diet of creatures that are. Their menu of mussels, limpets, and chitons are easily effected by changes in the environment. If oystercatchers aren’t healthy, it probably means that something significant has happened to the shellfish that they eat. Click on the image below to learn more about the black oystercatcher, a critical species of the Nearshore Benthic Systems in the Gulf of Alaska project. Click the audio icon to hear the call of the black oystercatcher. Scientists, like the National Park Service’s Heather Coletti, are trying to address the following questions: • Are the numbers of black oystercatcher nests changing from year to year? • Is the number of eggs or chicks in each nest changing? • Are chicks supplied with the same variety and amount of food each year? • Does this data change from one location to another? Heather and her team monitor the habitat of black oystercatchers using a variety of methods, including the use of shoreline transects to survey nest sites and sample prey remains at oystercatcher nesting sites. VIDEO: Monitoring Nearshore Systems Heather Coletti describes her work studying black oystercatchers for the nearshore systems component of Gulf Watch Alaska. (1:50) Video Transcript The nearshore is that interface between the terrestrial system – land – and the oceans. And there are several influences from the ocean that meet at the nearshore and then we have anthropogenic and natural influences from the terrestrial, and in some heavily populated areas that’s pollution and runoff, and how the nearshore really is affected by all those influences. And it’s essentially where the densest human populations live, along the coasts. Our program is essentially monitoring the nearshore food web. So we start out at the sea grasses and algae, which are the primary producers of that system. And then we look at invertebrates – benthic invertebrates – whether it’s mussels, clams, limpets… And then we have surveys for higher trophic level predators, like your sea ducks, sea otters, sea stars. We monitor oystercatchers, which are a pretty charismatic shorebird that is essentially confined to the nearshore and the intertidal. They feed exclusively in the intertidal on benthic invertebrates. So that’s your mussels, your limpets, that’s their two primary food sources, but they’ll eat some barnacles and some worms. So we have several aspects of their biology that we are monitoring. The goal of any monitoring program is to look at change over time and understand change over time, what’s driving it and if there’s any way to predict what those outcomes may be. That’s ultimately the goal and we are in our first few years of monitoring, and right now looking at what the natural variation in these systems is like. That hasn’t been fully documented yet.       Who is watching the Gulf?   Abundance (n): the quantity or amount of something   Benthic (adj): pertaining to the seafloor and the organisms that live there   Data (n): values for something measured   Density (n): the number of inhabitants per unit of area   Distribution (n): the way in which something is spread over an area   Intertidal (n): the benthic shore area between the extreme reaches of high and low tides   Nearshore (n): the marine zone that extends from the high tide line to depths of about 20 meters   Organism (n): an individual life form   Prey (n): an animal taken by predators as food   Riparian zone (n): the area of land next to a lake, river, stream, or wetland   Subtidal (n): the benthic area below low tide that is covered by water most of the time and exposed briefly during extreme low tides   Tide (n): the alternate rising and falling of the sea at a particular place, due to the gravitional attraction of the moon and sun   Transect (n): a path along which scientists count animal populations and plant distributions

The Pelagic Ecosystem team has the task of studying these predator and prey species in Prince William Sound. Despite the challenge, scientists have already managed to collect decades of data that focus on the interactions between whales, seabirds and their prey. This information is useful in answering questions such as: • What are the population trends of key open-ocean predators, such as orcas, tufted puffins, and humpback whales? • Are the numbers of forage fish, like herring, sand lance, and capelin, going up or down? • Is it possible to monitor forage fish population trends? • If it is possible to monitor them, what is the best way to do so? Forage fish have a big impact on marine ecosystems. They convert a huge amount of energy from lower trophic levels and this energy is transferred into food for larger fish, marine mammals, and seabirds. Forage fish have great numbers of offspring and short lifespans. These traits can cause major changes in their abundance from year to year. If the abundance of forage fish increases or decreases significantly, the predators that eat them will also experience shifts in their population numbers. Humpback whales are predators of herring. Many humpback whales migrate from Prince William Sound to Hawaii for the winter. Some humpback whales, however, stay in or near the Sound. During the winter, there is not much plankton for humpbacks to feed on, and fish like herring become a good alternative source of food for these whales. Watch the video below to see how the predators of the pelagic hunt their herring prey. VIDEO: Bait Ball Feast - BBC One In late summer, the plankton bloom is at its height and vast shoals of herring gather to feed on it. Diving birds round the fish up into a bait ball and then a humpback whale roars in to scoop up the entire ball of herring in one huge mouthful. From "Nature's Great Events: The Great Feast" by BBC. (1:14) Video Transcript The murres only attack from beneath, trapping the fish against the surface. But they push the herring within range of the gulls. It’s a feeding frenzy. The table is set for the mightiest predator of them all: the humpbacks have reached their feeding grounds. Scientists want to know the best way to estimate the numbers of specific fish species, such as herring. They get the data they need using a combination of aerial surveys, hydroacoustics, and various fish-capture techniques. Check out the video below to hear Mayumi Arimitsu explain some of these techniques. VIDEO: Forage Fish Studies Mayumi Arimitsu describes the methods scientists use to monitor forage fish populations. (0:55) Video Transcript We have observers in a plane that are looking at schools of fish in the ocean very close to the shoreline. We do a couple of things. One is use hydroacoustics from the boat, and with basically a scientific fish finder we’re able to quantify the biomass and density and depth distribution of these different forage fish. We also are trying to validate the aerial survey observations so we have a team in a skiff that are communicating with the pilot in the plane, and they are trying to catch what the observers in the plane are seeing. Scientists working on the humpback whale monitoring project are trying to understand if the whales are having an impact on the recovery of herring populations in Prince William Sound. An important part of this project is maintaining an up-to-date humpback “fluke identification catalog,” a kind of “Who’s Who?” in the Gulf of Alaska whale world. Watch the video below to learn about how scientists observe and photograph whales included in the fluke identification catalog. VIDEO: Tracking Humpback Whales John Moran describes how scientists are studying the importance of humpback whales in the Gulf of Alaska ecosystem. (2:08) Video Transcript (Narrator) These small silver fish are Pacific herring, one of the many species being monitored by Gulf Watch Alaska. Scientists are monitoring their population for signs of recovery after the Exxon Valdez oil spill. They are also interested in other potential factors that could be affecting their recovery. One of these potential factors may be humpback whales. (John Moran) We want to know if humpback whales are having an impact on the recovering herring population in Prince William Sound. Basically we want to know how many herring are whales eating, and is that important. So the first thing we need to do is figure out how many whales are there, so we use Photo ID. All the whales have unique patterns on their flukes. When the whale dives it shows the underside of its fluke, and we’ll take a picture of that and that can identify the individual whale. So basically we get on the boat and we go look for whales. That the base of our research is getting the fluke IDs. And from that you can get a lot more information out of it. We need to figure out what they’re eating, so we use the echo sounder on the boat, we’ll use nets and jigs, so we’ll see whatever prey is around the whale and try to catch that. Or if there’s any scales that slip out of their mouth, or any kind of sign of things on the surface, or fish jumping out of the whale’s mouth, we’ll try to document that. And we also use biopsies. We have a cross bow or a rifle that takes a little blubber plug out of the whale. So we approach the whale and get a little sample, and from that we can use stable isotopes or fatty acids to get at what the diet’s been from that whale. Humpbacks are kind of new players on the scene, they’re population was really low. In the late sixties & early seventies, there may have been 1,500-2,000 humpbacks in the North Pacific. And then there was this survey called the SPLASH survey that took place in 2006 that put the population at over 20,000. So that’s a huge increase. It impacts managers. If you’re managing a herring fishery and you have these humpbacks population weren’t really there 20, 30, 40 years ago, you’ve got to account for these new predators, how many herring are they taking, it’s all important to know if you’re trying to manage a fishery. We haven’t had them there, so how they impact the ecosystem is going to be new to us.       Who is watching the Gulf?   Biomass (n): the amount of living matter in a given habitat (i.e. the weight of organisms per unit area, or the volume of organisms per unit of habitat)   Forage fish (n): small schooling fishes that feed on plankton and are eaten by larger predators   Hydroacoustics (n): the study of sound in water   Pelagic (adj): the open sea, away from the coast or seafloor   Trophic level (n): the position of an organism or species in a food web or food chain

IMPACT (v) - to affect or change something else FORAGE (v) - to search for and collect food MIGRATE (of animal) (v)- to move seasonally from one area to another           Background Scientists know that when summer sea ice in the Arctic melts away from their shallow feeding grounds, Pacific walrus will haul out on land to stay near their food. The Icy Cape stampede showed scientists that land haulouts in the Chukchi Sea can be dangerous for young walrus. Scientists wonder how walrus populations will be impacted when the walrus have to use land haul outs more and more often. To understand how walrus populations might be affected by changes in their Arctic habitat, scientists first had to understand "normal" Pacific walrus behavior. Take a look at the videos and fact sheet below to explore what researchers already know about the mysterious Pacific walrus. VIDEO: The Pacific Walrus Understanding walruses' relationship with sea ice is important to understanding their behavior. (1 minute) Video Transcript Pacific walrus feed in relatively shallow water, hunting for small invertebrates on the ocean floor. In the Bering and Chukchi Seas, the continental shelf provides a vast area of shallow, rich feeding grounds for the walrus. Walrus haul out on sea ice or on land to rest between feeding trips. Although they are good swimmers, they don’t typically swim long distances, so they prefer to rest near where they eat. In the winter, arctic sea ice extends south into the Bering Sea, where large herds of male and female walrus spend the winter together. Then in the springtime, females and calves follow the melting sea ice north into the Chukchi Sea, while adult males separate from the rest of the population and migrate south to spend the summer in Bristol Bay. The male walruses in Bristol Bay typically haul out on land and feed near shore. In the Chukchi Sea, the females and calves spend their summer floating on the sea ice, drifting over the shallow continental shelf. In recent years, summer sea ice in the Arctic has melted beyond the edge of the continental shelf, leaving the females and calves without their traditional feeding and resting platforms.   WALRUS FACT SHEET (click to download .pdf) Female walrus and their calves use sea ice all year. They migrate to the Chukchi sea in summer because there is so much food available for them there. Watch the video below to hear Dr. Lori Polasek talk more about how females and calves may be affected if they can't haul out on sea ice and must move to areas on land, instead. VIDEO: Females and Calves Dr. Lori Polasek describes how females and calves might be impacted by hauling out on land instead of sea ice. (1.5 minutes) Video Transcript What are some of the possible impacts of females and calves hauling out on land instead of sea ice? There are several important facts about walrus that we had to understand before starting this project, and one of those is that land haulouts are primarily used by male walruses, of all ages, and ice is primarily used by females and calves. And the importance of ice, you can think of it as a mom and calf are floating around on a piece of ice and that keeps them moving across the water so it allows them to utilize different resources so they don’t impact a resource and completely deplenish [deplete] it. Also, by allowing them to float around, they’re not congregated together, where they’re more susceptible to predators, where then you allow the whole herd’s offspring to potentially be wiped out by a predator. It also takes your young, your offspring which are more susceptible to disease, and separates them from the population so that disease can’t spread as fast. So these new emerging haulouts with moms & calves packed together, then wipe out all of those protections of those calves by exposing them to disease as a group, by allowing them higher exposure to predators, and then by also having them together totally deplete resources in a localized area. Arctic sea ice extent is impacted by changes in seasonal and global climate. Walrus respond to changes in sea ice by migrating and adapting their behavior. Understanding how sea ice forms and why it melts can help scientists understand more specifically how walrus will be influenced. Check out the sea ice fact sheet below! SEA ICE FACT SHEET (click to download .pdf) This important background knowledge helped scientists from the Alaska SeaLife Center develop a research project studying walrus.

Scientists form hypotheses to explain something that they observed. Scientists then test the hypothesis to determine how true it is.               Questions   Dr. Lori Polasek is a marine mammal scientist. When she has a scientific question, she designs a research project to help her find answers. She wants to learn how walrus use land haulouts. Dr. Polasek works together with her team to decide which specific questions they hope to answer. With this project, the team wants to learn: How many walruses are using a haulout? How long are they at the haulout? How often do the walruses use a haulout site? They already know that walruses are easily startled by things like airplanes or predators in the area, so they also want to learn more about how walrus react to disturbances while hauled out on land. Watch the videos below to learn more about the questions and hypotheses Dr. Polasek plans to look at with her study. VIDEO: DR. POLASEK'S RESEARCH Questions Learn what questions Dr. Polasek had about walrus that made her want to study them. (1 minute) Video Transcript Why did you want to study walruses? I think walruses as a whole are a very interesting species, they’re very tactile and gregarious. Why I specifically wanted to look at this particular study with walruses is because we had the mortality event that you guys heard about in 2009, where with ice loss moms and calves moved onto a land haulout, and we don’t really understand how the population will interact with humans and other species while they’re hauled out. What questions did you have? The question that I wanted to specifically look at was: what causes walruses to abandon a haulout – what disturbs them – and then how long does it take for them to come back?   VIDEO: DR. POLASEK'S Hypotheses Dr. Polasek explains four hypotheses that she will be testing in this investigation. (1 minute) Video Transcript What are your hypotheses? For this project we have four primary hypotheses specifically looking at disturbance: 1. The first hypothesis is that the new emerging haulouts will have a different reaction than the established haulouts. 2. That ice extent will impact how the two different haulouts will respond to disturbance events. 3. That mother and calves using the new haulouts will have a different reaction to disturbance events than males that are using the pre-established haulouts. 4. And lastly, that the time for recovery from a disturbance event will be different with the females and calves on the new haulouts versus the established haulouts with males. To answer these research questions, Dr. Polasek and her team needed to come up with a way to consistently observe walrus on their haulouts. Join the researchers as they develop a plan for watching walrus.

"Watching Walrus" is a virtual field trip (VFT) designed to introduce students to the process of designing a scientific research plan.  Throughout this exploration, students watch videos, examine images, and read fact sheets as they follow real-life scientists into the wilds of Alaska to study Pacific walrus populations.  This VFT can be used in a number of ways.  Individuals may choose to navigate through the slides independently, learning about Pacific walrus and why changes in Arctic climate have scientists concerned about these animals.  Self-guided exploration can be completed in under an hour.  Alternately, teachers may wish to facilitate a structured experience using the curriculum supplements.  Overview for Teachers Grade Level: 5th-8th Time needed:  6-8 one-hour class periods Nutshell: Students will gain experience designing a scientific research plan while learning about an actual research project that studies Pacific walrus in Alaska. Objectives: After completing this virtual field trip, students will be able to: - Describe how the research plan they develop meets the objectives set out by Alaska SeaLife Center scientists - Explain how Arctic animals, like Pacific walrus, may be impacted by decreased availability of sea ice - Locate geographic features of the Arctic and subarctic oceans using a world map Background: Pacific walrus are a marine mammal species native to the Bering and Chukchi Sea area between Alaska and Russia. A member of the pinniped (fin-footed) family, walrus are ocean bottom feeders that can weigh up to one and a half tons. Walrus live along the continental shelf where water is shallow and food resources are plentiful. Floating sea ice provides females and calves with access to varied food resources, protection from predators, and isolation from disease. Though walrus are a social, gregarious species (males are known to haul-out together in large numbers), females with calves usually stay separate from the herd, depending on sea ice for their haulouts. As a consequence of warming Arctic climate, scientists have observed that sea ice in the Arctic Region is shrinking. This means decreased habitat for Pacific walrus, particularly for vulnerable segments of the population like females with calves. As a result of these changes in habitat, walrus have been observed hauling out on land in numbers rarely seen before. Not only does this make populations more susceptible to disease, predation, and depletion of food resources, it also means moms and calves are living in large herds rather than in small groups or pairs. Walrus are known to abandon a haulout upon disturbance (e.g., by the presence of boats, people, predators). In such cases, walrus move quickly from land into water when they are on ice. As walrus are observed gathering in large groups (as many as 14,000 walrus have been observed hauling out together) scientists are concerned about the increased consequences of such disturbances. Instances of stampede have been recorded, including that at Icy Cape (described in Watching Walrus), leaving hundreds of animals dead. Such events led scientists at the Alaska SeaLife Center to begin research observing Pacific walrus. Their intention is to increase the understanding of what causes these animals to abandon a haulout.  They are particularly interested in how the patterns in walrus response differ between established land haulout outs and newly emergent ones. The research of lead Marine Mammal Scientist Dr. Lori Polasek, Marine Mammal Research Associate Jill Prewitt, and Research Coordinator Terril Efird inspired this virtual field trip. Join us as we explore some of Alaska’s most remote coastline and work to learn more about how sea ice loss is impacting Pacific walrus. Throughout their exploration of Watching Walrus, students will engage in discussions, make observations, complete a research ma,p and design their own research plan for observing walrus as they use land haulouts.  To use this virtual field trip you will need: - Internet access, video-streaming capabilities - Access to Watching Walrus the virtual field trip - Projection system (with audio) to display VFT content or a computer lab - Teacher guide and corresponding curriculum supplements (arranged as PDFs in the right hand column of this page) Specials Notes to Teachers: Guide to State & National Standards addressed in this field trip (Click to download .pdf) Using the Virtual Field Trip Teachers may choose to have the class navigate through Watching Walrus as one large group, using a projection system to display content, or have students work independently in a computer lab setting.  All activities included in the curriculum supplements work best in a classroom setting with tables arranged into small groups. Using Curriculum Supplements We encourage teachers to read through the Teacher’s Guide and all Curriculum Supplements before beginning Watching Walrus with your students.  Some projects, like the Research Map, will be completed over the course of this exploration.  Videos and PDFs Many sections of Watching Walrus include embedded videos and .pdf documents.  Teachers may elect to print class sets of the .pdfs or use them digitally.  All .pdf files are 1-2 pages long.  Most videos are less than 3 minutes long (exact durations can be found in the description of each video).  Video transcripts can be accessed by clicking the video transcript button below each clip.  Vocabulary Important vocabulary terms are included in the VOCABULARY box in the lower right-hand corner of each section.  A complete glossary of terms is included as a .pdf in the FOR TEACHERS section.  Age appropriateness This virtual field trip is designed to meet Alaska state and National science content for students in grades 5-8.  We understand that students in grades 5-8 may display a variety of skill sets and reading levels; therefore, this grade distinction is designed only as a guideline.  The scientific process discussed in this virtual field trip is appropriate for and may be enjoyed by older students, as well.  Older students may progress through this virtual field trip at a faster rate than that outlined above.  Additional Resources: Web Resources: Walrus Natural History Alaska Department of Fish & Game (ADF&G): Walrus Profile Walrus Information from SeaWorld/Busch Gardens National Geographic Kids Creature Features: Walrus NOVA: How to Speak Walrus USFWS Species Info: Walrus ADF&G Walrus Island, State Game Sanctuary Sea Ice National Snow and Ice Data Center NASA Earth Observatory: Sea Ice Print Resources: For an overview of Pacific walrus facts, and information on other Alaskan marine mammals: Wynne, Kate.

On a ship the size of the U.S. Coast Guard Cutter Healy, several groups of scientists will be working on the boat at once, each with their own research project. Watch the video below to learn about what daily life was like as the research team collected samples for their sea ice project. VIDEO: A DAY IN THE LIFE Martin Schuster describes daily life working as a research technician on the sea ice project. (2:45) Video Transcript "My name is Martin. I've been a grad students at UAF (University of Alaska Fairbanks) in the Masters program in Marine Biology for about four years now. "In the sea ice project working with Rolf my role was as technician, so I was basically organizing our gear before we would go out, and making sure all our sleds were loaded up with all the various paraphernalia that you need to go out and dirll holes in the sea ice and sample water. Our project was to get off the ice breaker on either a little ladder that they would lower down to the ice, or with a helicopter, which was the preferred way to do it. My job was basically to pack all the gear before we got out. To double, triple check and make sure that we had everything, because once you're twenty miles away from the ice breaker, if you forget something it's not a good thing. And then once we got onto the ice we would unpack everything. We would take some ice cores and then we would section the ice cores so that we could look at each individual strata in the sea ice later on and determine what kind of biota is living inside there. We'd also cut a larger hole in the sea ice so we could lower a device called a ctd. This thing would basically give us various water temperature and clorofil readings as it goes down into the water and then we'd pull it back up by hand. Most of the work was definitely getting things together and then cleaning up afterword. You have a pretty limited time on the ice and you want to get as much work done as you can. And then as soon as you're done it's time to go back to the ship because of polar bears." Text on screen "Wait a second.... POLAR BEARS" Martin: "It was a worry, I mean whenever we were on the ice directly from the ship we had what's called a bear guard. It was a Coast Guard person, fully dressed up in their survival suit with a rifle. And they would stand and watch us the whole time, just to make sure there were no bears around. So it was expected that we would see some bears, but sadly we did not. "We were just out during the day which was really neat because we got to see every sunrise and sunset, which on the sea ice is just spectacular. It was really, really cool. Just go, go go all the time. Whenever there's a chance to work, we were working. You get into sort of a motion after the first couple days, and time just starts to fly by. You really lose all sense of what day it is in the week, because it doesn't really matter. You have your work cut out for you that day, you know what you're going to do. You set all your stuff out, and you just do it. One day just begins to blend into the next. And it's actually better to be busy on a ship like that than it is to be idle, because you can get bored pretty easily. At the end of the busy day there's still work to be done. Back on the ship, the scientists have to download data to their computers and store samples for later analysis. Finally, they repack the gear for another day on the ice. On the USCGC Healy, every day is a work day. The team will continue this routine each day for several weeks! The team is excited to begin piecing together the food web, but analysis will have to wait until later, back in the lab in Fairbanks.       WHO IS STUDYING SEA ICE?   BIOTA (n)- the animal or plant life in an area   CHLOROPHYLL (n)- a green pigment found in plants and algae

In addition to having the necessary sampling equipment, it was important that they time the research trips so they would be collecting samples during the spring sea ice melt season.  If they traveled too early, their measurements might underestimate the importance of ice algae. If they traveled too late, the ice would all have melted and there would be no ice algae for them to measure.  The team chose research sites in the eastern Bering Sea because it is a very productive region of water. Picking the research area was only the beginning. Next, they had to select the right tools to help them answer their research questions. Navigate through the images below to learn how each tool helped the team answer their research questions: With many samples to collect at every study site, a researcher's job is never dull.

Before scientists can be awarded funds to begin their project, they must design a detailed proposal explaining what they hope to learn with their study. This process begins with a scientific question and expands to include what the scientists expect to find, also known as a hypothesis. VIDEO: RESEARCH QUESTIONS Dr. Katrin Iken outlines the team's research questions for the sea ice project. (1:45) Video Transcript "My name is Katrin Iken, and I am a faculty member here in the School of Fisheries and Ocean Sciences at the University of Alaska Fairbanks, and my specialty as a faculty member is in Marine Biology. "A big question in this project is- what is the significance of the sea ice for the (eco)system, and what would it mean if sea ice were to go away if climate becomes warmer, so we need to understand what happens, how organisms react to this. My specific role was to look at loss of sea ice in terms of how important is that sea ice for the food web. "What I like about the benthic environment in a way is that it stays where it is. They don't move a whole lot. The conditions around it might change, but the organisms themselves actually stay in place. If you are a worm sitting in the mud, then you are sitting in that mud, you're not moving around a whole lot. Even if they move they often move over very small areas. That's very different than water column organisms that get just swept away with currents. "So if I am interested in how do conditions in a certain region change over time, again we are investigating quite a bit of climate change related scenarios, then having something that stays in place and is exposed to changing conditions, you can actually look at how changes are reflected in those organisms." Scientists hypothesize that the algae that grows on sea ice is an important food source for primary consumers living in the pelagic and benthic zones. They are concerned that, as ice conditions change as result of changing climate, it will affect the species that rely on this ice algae. The problem is, little data had been collected in the past, so not much was known about how much ice algae grows in the Bering Sea in spring or which species of animals were eating it. During the spring of 2008, 2009 and 2010, Dr. Gradinger and his colleagues completed field work in the eastern Bering Sea in an effort to answer these questions with financial support from the National Science Foundation (award 0732767). In order to test their hypotheses, Dr. Iken and the other scientists had to develop a plan. How would they get to the Bering Sea?  What tools would they use to sample and study the ice and the ice algae?  How would they discover which species were dependent on sea ice and how the food web fit together?  All of these challenges had to be carefully considered before the team even traveled to the field. After all, once you’re out in the middle of the Bering Sea, there’s no going back for something you forgot!         WHO IS STUDYING SEA ICE?   PROPOSAL (n)- a plan put forward for consideration; in this case, a science project   HYPOTHESIS (n)- a proposed explanation to a question that must be tested   FOOD WEB (n)- all the interconnected food chains in an ecosystem   DATA (n)- factual information

There are no roads and your tent could be the highest point on the horizon. Trekking though the swampy tundra of the Yukon-Kuskokwim Delta (Y-K Delta), scientists are on the lookout for nests. Counting every species they encounter, one bird eludes them all: the Steller's eider. This mysterious bird is a rare sight for researchers across Alaska. Surprisingly, one of the best places to observe these birds in Alaska is at a facility that is located hundreds of miles from their natural habitat. Watch the video for a glimpse into the strange lengths that scientists are going to in order to learn as much as possible about the elusive Steller's eider. Can you guess what the researchers are doing - and why? VIDEO: Mystery on the Tundra Scientists are going out of their way to learn more about Steller's eiders. (1:34) Why are scientists going to such great extents to learn more about the Steller’s eider? The number of Steller's eiders in the wild are declining. While two breeding populations exist in northern Russia, the breeding population of Steller’s eiders in Alaska has all but vanished and is now classified as Threatened under the Endangered Species Act. No one knows why these birds started disappearing in the 1970's. Scientists have proposed a few possible explanations, such as lead poisoning from ingestion of spent lead shot; increased predation from gulls, foxes and ravens; and changes in the coastal environment. As temperatures warm and sea levels rise near the eiders' preferred habitats, will the few remaining pairs of birds continue to be successful nesting in Alaska? Concerned for the Alaskan population, scientists collected Steller’s eider eggs from Barrow, Alaska in an effort to prevent a complete disappearance of breeding eiders. With these eggs, the scientists have created a captive-breeding “reservoir” population. This breeding population resides at the Alaska SeaLife Center in Seward, Alaska, where researchers and aviculturists have the skills to keep the birds healthy while they learn more about this rare species. VIDEO: Introduction to the Research Project Dr. Tuula Hollmen describes the Steller's eider research project and its overall goals. (1:51) Video Transcript My name is Tuula Hollmen and I am a research professor at University of Alaska Fairbanks and a scientist at the SeaLife Center. I have been working with birds for, I think it is over 25 years now. The main goal of the eider research program is to help support the recovery of eiders in Alaska and the main focus of the program at the SeaLife Center facility right now is the captive breeding program. One of the main goals of having the eiders here is to help buffer the species against extinction. We are also collecting a lot of data throughout the year to help learn more about the basic biology and physiology of the species. The third big goal for that program is to develop captive breeding techniques for Steller’s eiders with the potential that those methods that we develop could be used in the future in a field program to help augment or reestablish a population by using reintroduction as a tool. The Steller’s eider is a unique arctic species. It is the only species in its genus, Polysticta. There is no other Polysticta species. So if we lose the Steller’s eider we lose not just a species but a genus. I think that everything that I have been learning about the species just makes me more convinced that they are a unique species. I think the world will be a different place if we lose this unique species that is not necessarily similar to any other species. Dr. Tuula Hollmen has been studying Steller's eiders at the Alaska SeaLife Center since 2001. Her project allows scientists to keep their eyes on eiders, to observe and learn about a bird rarely seen nesting in the wild.       CLICK BELOW TO LEARN ABOUT SEADUCK SCIENTISTS!   AVICULTURE (n) - the raising and care of birds (especially wild birds) in captivity.   ENDANGERED SPECIES ACT (n) - signed on December 28, 1973, this act provides for the conservation of species that are endangered or threatened throughout all or a significant portion of their range, and the conservation of the ecosystems on which they depend.   ECOSYSTEM (n) - a system formed by the interaction of a community of organisms with their environment.   INGEST (v) - to take something into your body (such as food).   LEAD SHOT (n) - small pellets of lead that are shot from a shotgun; used for hunting birds and small game.   PHYSIOLOGY (n) - the way in which a living organism or bodily part functions.   RESERVOIR (n) - an extra supply of a resource to be used when needed.   SPECIES (n) - a group of animals or plants that are similar and can produce young.   THREATENED SPECIES (n) - any species that is likely to become an endangered species within the foreseeable future.   TUNDRA (n) - a flat or rolling treeless plain that is characteristic of arctic and subarctic regions; subsoil is permanently frozen and dominant vegetation consists of mosses, lichens, herbs, and dwarf shrubs.

The eider team monitors the birds’ behaviors and health on a daily basis and makes sure the birds have the proper space and food. The enclosures for the birds aren’t exactly like the habitats they typically live in, so it is up to the husbandry team to figure out what the Steller’s eiders need to succeed. Dr. Tuula Hollmen and her crew work hard to create a habitat that suits the eiders. Remember, Steller’s eiders are migratory birds, so the habitat at the Alaska SeaLife Center has to change season to season, especially during breeding season! VIDEO: Creating a Virtual Habitat Tasha DiMarzio explains how the Steller's eider enclosures at the Alaska SeaLife Center can be altered to create a virtual tundra habitat. (2:19) Video Transcript The area we are sitting in now we call our breeding units. There’s ten individual units or one large unit, and we can create smaller flocks or individual breeding units or one big pen for if we want to winter everybody in this unit, we can do that. Starting in January through March, we’ll really start watching the birds and seeing who is courting with who and who’s pairing off, and then we’ll move them from what we call the non-breeding or wintering unit and they migrate over to our breeding units (which is just across the walkway). In the winter time we switch them all to salt water because that is where they would be in the wild, out in the ocean, and in the summertime they come to these freshwater tundra ponds. When we were in full breeding season we had covers over one of the pools and it was tundra and then pond on the other side. But now since we are in duck rearing mode we have two ponds and they’re both fresh water. Getting birds to breed in captivity is always a big challenge. Luckily we are in a state where these birds are actually from, and so we can go out and see what they are using as nest materials and what sites they prefer, if its grass or lichen, and then we try and replicate that the best we can. We don’t have these big vast tundra fields, so we try and create areas that they can feel secluded and have privacy, but then have it look a little bit like what maybe they would see in the wild. We go to the beach and we collect a lot of driftwood to create visual barriers and blinds and areas that they can be private. Because each female is picky about where she likes, we try and provide each pair with at least three different nesting options. So a nesting option can be a manmade wooden structure that looks like nothing that you would see in the wild, and then another open tundra-like moss nest, and then a combination of the two: maybe driftwood around a plexiglass-covered structure. And then the biggest key is just keeping it dry so that the down in the nests stay dry. Because the areas that they are nesting, even though it is Arctic tundra, it’s actually a desert and so there is very little water and rainfall but here we’re in a very rainy climate and so that’s a big challenge we have, is keeping their nests dry while they’re going through the egg laying process, so we come up with different things to try and tackle that challenge. By altering the virtual habitat, the husbandry staff can try to match the eiders’ needs for the breeding season. Each year, the husbandry team continues to offer the eiders a variety of space and nesting configurations in the habitat, in an attempt to promote successful breeding. If something doesn’t work, they try something different the next year! After years of trial and error, favorable conditions have been created, allowing some of the eiders to feel comfortable enough to nest! As a result, the team is faced with hundreds of eggs. Some of the Steller’s eider hens incubate their own eggs, but many eggs end up in the care of the husbandry staff when hens don't prepare an appropriate nest. See how scientists can try to play the role of a hen incubating her eggs. VIDEO: ARTIFICIAL INCUBATION Nathan Bawtinhimer describes the process involved when humans incubate eider eggs. (1:32) Video Transcript It's a fun challenge trying to get the artificial incubators to accurately mimic the hen incubating which is very tricky. So we’ve been messing around with a lot of different humidity settings and different methods of turning to more accurately imitate the hen and promote better development within the egg during the incubation process and successful hatching. It’s important that we candle the eggs regularly so we can keep track of the development inside the egg. By candling them with a bright LED flashlight we can actually see inside the egg and just by looking we can tell how long it’s been incubating for, if it’s on the right track developmentally, and what the estimated hatch should be. When we are candling the eggs it is actually an important cool down time for the eggs, because we’ll have the top off the incubator which simulates the hen getting off the nest and foraging. And we also weigh the eggs everyday because during the course of incubation there is a certain range that the egg is supposed to lose to hatch successfully, usually between 12 and 16% of its weight. So we watch their weight loss and we adjust the humidity accordingly. The amount of weight they lose is critical for successful hatching. We’ll record and enter all the data in the spreadsheet so we can track the weight loss and the development of the eggs. And we keep very detailed records of everything we see every day when we candle. While scientists are learning about the Steller's eiders at the Alaska SeaLife Center, they also need to learn more about the natural habitat of these birds. If researchers are hoping to increase the nesting population of Steller's eiders in Alaska, there has to be suitable nesting habitat available in the wild. To determine what is available for these birds in the wild, the scientists head out into the field...       CLICK BELOW TO LEARN ABOUT SEADUCK SCIENTISTS!   COURTSHIP (n)- the behavior of male birds and other animals aimed at attracting a mate.   HABITAT (n)- the natural home or environment of an animal, plant, or other organism.   HUSBANDRY (n)- the care, cultivation, and breeding of crops or animals.   INCUBATE (v)- to keep an egg or organism at an appropriate temperature for it to develop.   MIMIC (v)- to imitate something.   MONITOR (v)- to keep surveillance over something.

Each year presents a new opportunity to learn about Steller’s eiders and to grow from past successes and failures. Researchers are expecting another breeding season with hundreds of eggs. They are hoping that they have determined a good setup for the eiders at the Alaska SeaLife Center so more hens will be able to go through the complete incubation process, as Scarlet and Eek did in the summer of 2014. Dr. Tuula Hollmen is hoping to breed “tundra-ready” ducklings that would be able to survive on the tundra, should reintroduction become a reality. If wildlife managers decide that reintroduction is necessary to help these birds recover, the scientists at the Alaska SeaLife Center now have the tools of captive breeding necessary to help make this possible. Reintroduction would present a whole new set of questions for the team. How will they get their rearing techniques to work in the field? In a release facility, they would have to try to repeat what goes on at the Alaska SeaLife Center in the remote setting of the Y-K Delta. Since they would be on the tundra, there would be less manipulation of the habitat, but there wouldn’t be a lab nearby for immediate analysis. Also, Steller’s eiders are migratory birds, so they will travel from the place they are released. How will researchers help released ducklings establish winter and molting grounds? How will they get the eiders to return to the Y-K Delta for the next breeding season? Text goes here! Reintroduction of other bird species has been done successfully, but each species has its own specific needs. As this project continues its trek forward, Steller’s eiders will keep scientists questioning.

Use "divobj.id" to get its ID //state: "block" or "none", depending on state } animatedcollapse.init() The Gulf of Alaska is part of the North Pacific and reaches from the Alaska Peninsula in the west to the Alaska archipelago in the southeast.  The coastline includes mountains, glaciers, temperate forests, towns, and cities. Powerful currents in the Gulf of Alaska have helped shape the surrounding land and communities, and circulate necessary nutrients and marine life from the deep waters to the surface. These circulation patterns allow the Gulf of Alaska to thrive with life and sustain some of the largest United States’ fisheries, as well as provide essential habitats for seabirds, marine mammals, and fish to feed and reproduce. As described in Gulf Watch Alaska: Long-term Monitoring, the Gulf of Alaska was impacted by a major oil spill on March 24, 1989. The Exxon Valdez oil tanker ran aground in Prince William Sound, Alaska, and spilled nearly 11 million gallons of oil. An estimated  250,000 seabirds, 2,800 sea otters, 300 harbor seals, 250 bald eagles, up to 22 orcas, and billions of salmon and herring eggs were lost to the spill. Since the spill, scientists have been conducting a long-term ecosystem monitoring study to gain a better understanding of both natural and human-caused impacts to the Gulf of Alaska ecosystem. The Gulf Watch Alaska long-term monitoring program consists of a team of scientists who work together to measure and watch different parts of the ecosystem spill area. Through cooperation in this project, scientists can see the links, or connections, between all of their areas of study. In science, we call this “systems thinking.” Systems thinking looks at the web of relationships where individual pieces respond on their own and together as a whole. An ecosystem like the Gulf of Alaska is not just a collection of individual animals and plants. It is all living things interacting with each other and with the non-living components around them that drive physical and chemical processes and affect the conditions for survival. The process of systems thinking allows the Gulf Watch Alaska team to harness the power of a network of scientists that all specialize in different research subjects. This power makes the team of scientists well-equipped to solve any mysteries unfolding in the Gulf of Alaska. One such mystery arose in 2014 when people across the Pacific West coast began to notice large quantities of dead or dying birds washing up all along the shore from California to Alaska. As this event expanded, scientists began investigating the intricate network of natural processes in the Gulf to try and uncover the mystery of these dying birds. Yosty Storms is a former colleague at Gulf Watch Alaska. She is now working for the Alaska Native Science and Engineering Program in Anchorage. Recently, Yosty has heard a lot of talk regarding the birds washing ashore, as well as other very unusual events happening throughout the Gulf and surrounding land areas. Let’s follow along as Yosty visits with the Gulf Watch Alaska team and investigates these odd occurrences. Watch the video below and meet Yosty! VIDEO: Meet Yosty Storms Meet Yosty Storms and learn about a mystery occurring in the Gulf of Alaska. (1:42) Video Transcript Narrator: Meet Yosty Storms. Yosty works at the Alaska Native Science and Engineering Program in Anchorage. But when she was a student she worked with Gulf Watch Alaska. That's a long-term monitoring program looking at a large range of the North Pacific Ocean, especially the area impacted by a massive oil spill back in 1989. This area has taken a very long time to recover, because some of that oil is lingering on the beaches and offshore. That oil continues to affect the health of fish and other wildlife. Gulf Watch Alaska is a team of amazing scientists who are "on watch" for this ecosystem, keeping tabs on its recovery from the oil spill, and to see if they can detect other sorts of changes – the kinds that might be the result of global climate change. The majority of Alaskans live in communities along the coastline of the Gulf of Alaska, or within the watersheds that drain into it. Some of these communities, like here in Cordova, are dependent on the Gulf of Alaska for their local economy and jobs. Others, like the Native Village of Eyak, have over 10,000 years of history in this region. Everyone at Gulf Watch Alaska agreed that 2014, 2015, and 2016 were very, very unusual years for the ecosystem. So let’s go along with Yosty to see if we can put the mystery together. The first question Yosty wanted to ask some of the scientists was: just how unusual were these years?         Who is watching the Blob?   Archipelago (n): a section of water containing many islands   Cooperation (n): working together to accomplish a goal   Ecosystem (n): a community of living things and nonliving surroundings linked together by energy and nutrient exchange   Essential (adj): something that is necessary or very important   Habitat (n): a place that provides an animal or plant with adequate food, water, shelter, and living space to feed, breed, seek shelter, and raise young   Intricate (adj): very detailed, complex   Lingering (adj): sticking around, lasting for a long time   Sustain (v): strengthen or support physically or mentally   Thrive (v): to be healthy and successful   Watershed (n): an area of land that contains a common set of streams or rivers that all drain into a single larger body of water, such as the ocean

And of course, getting outdoors when possible, to recharge interest and enthusiasm, even get new ideas." Challenges in her work: "Obtaining the support needed for a scientific project, especially something long-term, takes an enormous amount of time and effort - and is usually not why one goes into science. But it has to be done... these aren't the fun aspects of science, but they also help you to refine your goals, objectives, and approach." Kathy's advice to young people interested in science: "Get some field experience, and even work on several types of studies to see what really stokes your interest in learning more. Often, biologists start out as volunteers (I did) and move to seasonal field work, or help with data and reports. When you're on a project, do some background searching and reading on the subject or your specific project (so easy to do these days), and find out what questions the project leader is focused on. If you do a good job, work well in difficult conditions, and stay in contact, chances are you'll be called back." Dr. Kathy Kuletz describes her career as a seabird biologist. (3:14) Video Transcript I’ve always been interested in the working with wildlife. I grew up in the desert, so the ocean was exotic to me. Anything that had to do with the ocean was very exotic, and that’s probably what attracted me to that aspect. I wanted to see Alaska, so I came up for a summer job like most people here. I worked in fisheries to begin with because that’s where a lot of the jobs were – there’s not a lot of funding to study birds. I was doing fisheries work, but then I wound up getting a summer job on Naked Island in Prince William Sound, and that was my first job with seabirds. My one year there turned into four, which turned into my Master’s degree studying pigeon guillemots there. Of course that was before the oil spill – I started back there in 1978. After the oil spill, it turned out that was one of the few places where we had some baseline data on seabirds – how they raised their chicks, what they fed on, and how many birds there actually were in these colonies. I went back after the oil spill, again as a seasonal employee of Fish & Wildlife Service, and eventually it became a term appointment. I stayed on in prince William Sound studying marbled murrelets. I became interested in what was going on at sea. Back in the 70s and 80s there was a large ecosystem study going on because they were looking at oil lease sales in the Bering Sea and the Gulf. They had what they called the OCSEAP program – the Outer Continental Shelf Environmental Assessment program. Then there was a huge gap where not much was done out at sea, and of course seabirds spend most of their lives out at sea, but mostly people study what goes on at a colony. I was interested in that other aspect of their lives and what happened the other three quarters of their lives out at sea. For the most part, this was before we had little tiny satellite tags and GPS dataloggers, but we didn’t know what they really did. We didn’t have a good idea of where birds went, and a large part of what we found out was by counting birds at sea – going out on big ships, research vessels that were doing fisheries work or oceanographic work, and doing surveys in conjunction with those. That’s what we’ve continued to do, of course we have more technology now and we can log location of every sighting very accurately and tie that data into what the oceanographers found on the same cruise, or the plankton people, the fish people, the marine mammal folks. So we’re trying to identify the hot spots, trying to found out where birds go in the non-breeding season as well as during the breeding season offshore. That’s what’s attracted me – the idea of being able to put together all this information and understand the big mystery of what seabirds do out at sea, that’s what draws me into it.   Who is watching the Blob?

The Alaska SeaLife Center and Gulf Watch Alaska are excited to present this virtual field trip (VFT)! Join the Gulf Watch Alaska team of scientists as they discover the mechanisms behind a mystery unfolding in the Gulf of Alaska. Learn about the work of a collaborative team of scientists from many different ocean science disciplines, and follow along with the narrator as she explores the scientists’ process of initially observing unusual phenomena in the Gulf of Alaska and seek to discover the causes and connections. You can use this VFT in conjunction with the “Gulf Watch Alaska: Long-term monitoring” VFT, or as a stand-alone piece. GRADE LEVEL: 6-8th TIME NEEDED: Between one and four 1-hour class periods (teachers may choose to use all or only some of the supplementary lessons). NUTSHELL: Students will learn about the mystery of the seabird die-off that occurred in the Gulf of Alaska, during the winter of 2015 – 2016. They will explore various aspects of the investigation and how, collectively, the scientists were able to begin uncovering the mechanisms behind the extreme die-off event.   LEARNING OBJECTIVES: After completing this virtual field trip, students will be able to: • Understand the process of scientific thinking and the use of the Scientific Method as a tool to develop questions and search for answers. • Understand the collaborative nature of science and how researchers from various disciplines working together can provide a ‘big picture’ view of a dynamic marine ecosystem. • Explain how an ecosystem is composed of many different components, including physical and chemical processes that drive the ecosystem and determine the conditions for survival of marine life. • Use evidence to make a claim about the cause or causes of a change in a population. BACKGROUND: In this virtual field trip, students will meet various scientists and researchers working for the Gulf Watch Alaska long-term ecosystem monitoring program, a project of the Exxon Valdez Oil Spill Trustee Council, investigating the marine ecosystems since the 1989 oil spill. This program focusses on a recent mystery that has unfolded in the Gulf of Alaska, beginning with the observation of an extreme seabird die-off event. Organized into three main pages, this VFT follows researchers along on an investigation to uncover what caused this mortality event. This VFT can be used in a number of ways. Individuals may navigate through the pages on their own and meet the scientists through the links provided on the right-hand bar. Self-guided exploration can be completed in a couple of hours. Alternatively, teachers may facilitate a structured experience, working through each page of the VFT together in class. Lesson plans (links included on the right-hand column of this page) are available to supplement online content. TO USE THIS VIRTUAL FIELD TRIP YOU WILL NEED: • Internet access, video streaming capabilities • Projection system (with audio) to display content or a computer lab (with headphones) • Corresponding lesson plans (linked as PDFs in the right hand column of this page) UNABLE TO RUN THE STREAMING VERSION?

Overview The ASLC  Wildlife Response program responds to live and dead marine wildlife that has been abandoned, stranded, or injured throughout Alaska. The ASLC is the only institution authorized to rehabilitate live stranded marine mammals in the state. We operate under permits and agreements issued by the National Oceanic and Atmospheric Administration (NOAA) and US Fish & Wildlife Service (USFWS). ASLC plays a critical role in responding to oil spills or other unusual events. In addition to covering the live animal response and care during the ‘busy’ season, May to September, ASLC remains in a ready state year round to provide basic animal care for oil-affected animals and deploy a mobile treatment and rehabilitation enclosure. The ASLC Wildlife Response Program is an important part of the Center's commitment to generate and share scientific knowledge to promote understanding and stewardship of Alaska’s marine ecosystem. The main goal of this program is to learn from live and dead stranded animals to better understand wild populations and maintain capacity to respond to natural or manmade disasters. We accomplish this by: Screening for conditions of concern Determining the health of individual animals Providing humane animal care Training staff and partners for response When possible, returning healthy animals to the wild

Stranding Network The Alaska Stranding Network is a group of dedicated volunteers and organizations that help support rescue, stranding and rehabilitation efforts statewide. Participating organizations include the Alaska SeaLife Center, Alaska Department of Fish and Game, National Marine Fisheries Service, National Oceanic and Atmospheric Administration, the North Slope Borough, the U.S. Coast Guard, the U.S. Fish and Wildlife Service, the University of Alaska Fairbanks and University of Alaska Southeast, as well as representatives from native communities and oil companies.   The Alaska Stranding Network works with the Marine Mammal Health and Stranding Response Program (MMHSRP) of the National Marine Fisheries Service (NMFS) to maintain and meet the following objectives: Improve the rescue, care and treatment of stranded marine mammals. Reduce the health risk to animals, humans, and the ocean environment during response to, and rehabilitation and release of, stranded marine mammals. Collect life history, biological, and biomedical data from live and dead stranded marine mammals. Develop baseline reference data on the health of wild marine mammal populations, normal stranding rates, and causes of morbidity and mortality; improve the rapid detection of morbidity and mortality events. Collect archival samples for future retrospective studies on causes of mortality or illness, including genetics and genomics, and for placement in the National Marine Mammal Tissue (and Serum) Bank and other properly curated, professionally accredited archival facilities. Refine and/or utilize comprehensive and consistent guidance for the rescue and rehabilitation of stranded marine mammals, collection of specimens, quality assurance, and analysis of tissue samples.
