Ever wonder what lies beneath the polar ice? Turns out several researchers did as well. This past July a team of scientists led an expedition designed to image life under sea ice. The video below was captured with the Nereid Under Ice (NUI) vehicle and shows brown algae living on the bottom of sea ice as well as larvaceans, which are filter-feeding tunicates. The advantage of the new vehicle is that it can travel very far (the spools of cable are ~40 km long) and allows researchers to create maps and collect samples. Researchers are hoping to explore greater distances in future dives that will explore beneath ice shelves and glaciers.
