 A lot of the research that we do is year round. So it's really useful to continue to collect the data through the darkness. Things that I'm specifically studying are all the ocean properties. And then we also dive year round here. So we're currently at the moment, we're waiting on the sea ice to be thick enough to dive underneath. But in a few weeks time, we'll get a chainsaw, cut a hole in the sea ice and dive underneath the sea ice.
