Back at South Base to check up on some seals as part of one of our surveys, making sure they're all tagged (which they weren't...there were 4 new pups along with 2 adults that needed tagged) and accounted for.

Jesse, we love the pictures of the seal,pups and what it is like in Antarctica. We are wondering - who does the diving, and what are they looking for? Do you know any of those crazy divers? We can't imagine having to do that! Also I appreciate it when you use hard words like "atypical" building vocabulary is awesome!ReplyDelete
Hey Mark and Students!Delete
The crazy divers are a bit crazy, I've met a few of them. To be a diver here, you have to be willing to let your face go completely numb from the cold (because the skin on their face is the only thing exposed!)! It is very cold under the water, but it is so incredible below the ice that the divers keep diving in! The divers do all sorts of things...often a research group will ask for a diver for help. For example, the sea urchin research team uses divers to collect sea urchins from the sea floor. Or another weddell seal research team uses divers to get video and photography of seals under the ice. Or a geology research time might want a diver to collect sediment on the floor of the ocean.
This looks like a cool video of one of the crazy divers (though I haven't watched the full video!): http://www.youtube.com/watch?v=d7gkPLTnAQs
That video is perfect! Thanks! We will watch about 4 minutes of it.Delete
