Walruses use sea ice as platforms on which to nurse their young and launch their dives for clams and other bottom-dwellers. Each spring, walruses move northward to stay close to these perches as ice melts in the south -- but as more and more sea ice melts because of climate change, they may not...
Cold Water Diving with WHOI
Jul 15 2011 - 5:00pm
"Cold-Water Diving: Going to Extremes for Research" is a video produced by Woods Hole Oceanographic Institution (WHOI) that shows the focus needed to do scientific work in cold water. The gear is bulkier and heavier, cold affects dexterity and capacity, and dives must be shorter yet still get the...
ROV Video of Stunning Creatures
