Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
The Ross Sea, a 1.9 million square mile (3.6 million square km) stretch of ocean off the coast of Antarctica, has been nicknamed “The Last Ocean.” And it’s not just a ploy to get your attention. In...
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...
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...
Using an ROV (Remotely-Operated Vehicle) equipped with a high-definition video camera, scientists can observe the life that flourishes beneath the Arctic ice . On this expedition, they discovered...

"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...
Chrysaora melanaster , one of the largest jellyfish commonly found in the Arctic, swims underneath the Arctic ice . Its tentacles can stretch to more than 3 meters long and pack a mean sting for...
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...
In the icy waters of the Arctic , a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost...
Ice divers use a quadrat to study the density of creatures living on the underside of Arctic ice floes. A quadrat is a standardized square used to take sample measurements that allow researchers to...
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...
It takes special equipment and many warm layers of clothing to dive safely beneath Arctic sea ice . Ice divers look for holes in a melt pond in order to enter the frigid waters.
An isopod stands on top of a glass sponge, extending its legs to find zooplankton. This delicate sponge is small, but some glass sponges can grow to the size of a 50-gallon drum and live for...
