To people living in warm climates, all ice looks the same. But if you live day-in and day-out on sea ice, like the Inupiaq people of Alaska, you would find that there are many kinds of ice, all...
Small Adélie penguins live throughout the Antarctic, but are most abundant in the area of the Ross Sea. They lay eggs on the few rocky outcrops of land not covered in ice. Scientists have determined...
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...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
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...
