In Antarctica, every day is a work day! If weather permits, the team is up early prepping their gear. Then it's out to the ice for a day of tagging or recapturing seals. When weather conditions are poor, the team spends their time catching up on lab work, downloading data, and maintaining equipment.
Watch the video below to learn more about what daily life was like for one of the researchers on this project.
VIDEO: A DAY IN THE LIFE
John Skinner discusses his daily routine as part of the team working with Weddell seals in Antarctica. (4:21)
My name is John Skinner, I’m a Research Associate here at the Alaska SeaLife Center, and I was a part of the team that went down there for this research. Mostly as a logistics coordinator, meaning that I was the one who coordinated all the stuff that we were using out in the field to make sure that it made it from McMurdo station out to the site safely, and that the equipment was being set up properly. A typical day for us was we would start somewhat close to mid-day, because that’s actually the optimal time to find animals hauled out on the ice. We’d get our gear together at the lab and then we would hand carry it out to what they call the Ski-Doo line, where all the snow machines are lined up. My job was to unbury them after the last storm, get them running, warmed up and ready to carry the group out to the field site.
Part 1: The Capture
When we get out to the site, we have all our equipment and we’ve identified an animal that we’re going to work with that day. One of the huge advantages of the Weddell seals is they just don’t have a response to predators, they don’t really understand that there’s anything dangerous about us.
So often a capture event just consisted of walking up to the animal, taking a look to make sure it’s safe for us to approach, and safe for the animal for us to approach, and then taking a large hood, and then sliding it over their head. As soon as the hood goes over they just lay there, and it’s done. They don’t fight, there’s no struggle. We send the vet in and then sedate the animal to make sure that they would be safe to work with. Then my job would kick in, that’s when I would unload the hundred or so pounds of gear and set-up our tripod over the top of the animal and get the animal into a sling, a net the animal could be rolled into, and then hoist the animal into the air and get our weight, our mass. Once we got that mass we would bring out our big tent which was this very compact-when-stored system. We would fold it out, and then basically envelope the people and the animal inside of this tent. Once this was set up we’d work within there safely and actually it was pretty warm inside.
First off we would get a blood sample and then we would go ahead and do some measurements of the animal. We need a length and a girth. Then we would start to prep the animal to put the instruments, the data loggers that we use, onto the animal. We had several heat-flux sensors along the animal’s body, at different locations where we’re trying to capture the distribution of heat that the animal is giving off. Then it was just about waking the animal up, making sure that they were happy and healthy before we were willing to let them go off on their own and enter the water again.
Part 2: The Recapture
When we leave the animal we have a plan for how long they need to stay out in the water for us to collect enough data. So we could sit there at our desks and track the animal’s progress and we had a schedule of when we planned to pick the animal up, but if we saw them moving out towards the open ice edge there was a good possibility we could lose the animal for good and never get those instruments back. So we would track them on a daily basis and see where they were going and then decide pretty much each day a schedule of who we needed to pickup and what a priority that animal would be. We’d start out with a GPS coordinate that we could get from this ARGOS, which is the on-board instrument's tracking system, to head out and we knew approximately where we needed to go. Once we got within a kilometer or two of the animal’s actual location (according to ARGOS) we would use signals from the VHF portion of that, we could track using a handheld antenna. Once we located the animal’s position we would go in and basically assess the situation from a distance, sneaking in and kind of cutting off its path to the water and then putting the hood on it and getting the instruments off and then, just sigh of relief. We don’t stop. Our research is every day, there are no weekends down on the ice.
Once back at the station at the end of the day, there's more work to be done. Scientists examine their data, sort and store samples, and clean and repack their gear. Finally, it's time to head to the dining hall, then off to bed to rest up for another day. Scientists come to Antarctica ready to work hard - and the team will continue this daily routine for nearly two months!
When the summer melt makes working conditions on the sea ice unsafe, it's time to pack up and return home. Once back in their labs, the science team can finally sit down and begin the process of interpreting their results.
