The threat that climate change poses to polar bears has received a lot of attention, but they are not the only Arctic species at risk. Ice-loving seals, such as harp, hooded and ringed seals, are...
The elegant Antarctic minke whale feeds on krill (tiny crustaceans) during the winter. Groups of minke whales often are found on the edges of pack ice feasting so that they can grow thick layers of...
Humpback whales ( Megaptera novaengliae ) are the most abundant baleen whale in the nearshore waters around the Antarctic Peninsula. They, along with millions of penguins, seals, seabirds, and other...
Sea ice is typically viewed as the domain of physical and natural scientists, the oceanographers, marine biologists, climate modelers, and navigators of the world. It is easy to forget another...
"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...
Weddell seals grind their teeth on holes in the ice to keep them open to their comings and goings between ocean and air. Their dives can last over an hour when they are looking for an opening in the...
The bowhead whale has a massive, bow-shaped skull to break through thick Arctic ice, and more blubber than any other whale.
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...
Standing at twice the height of the Adélie penguins, emperor penguins are the largest of the penguin species and can grow to be 100 pounds. This species breeds directly on the ice: a female lays her...
