Small amphipods, the blue bug-like creatures, can be seen here catching a ride on this enormous sea spider as it makes its way across the bottom. Many Antarctic creatures, like the dinner-plate-sized...
In Antarctica's Southern Ocean swims a beautiful polychaete (bristly worm) called Tomopteris carpenteri , which is adorned with alternating red and transparent bands. The largest species in its genus...
On average, Arctic sea ice has decreased by four percent per decade since the late 1970s. But at the same time, Antarctic ice has increased by 1 percent. Scientists are investigating why . More about...
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 National Ice Center’s work is focused on ensuring safe and efficient navigation, but it also supports scientific research and provides crucial information used by scientists to better monitor and...
Scripps scientist Gerald Kooyman's expeditions have documented climate-induced changes to emperor penguin habitat in Antarctica. Learn more about life at the poles or check out this emperor penguin...
For two months, Cassandra Brooks , a marine scientist with Stanford University, travelled on an ice-breaking ship through the Ross Sea in the Antarctica—and she filmed the whole thing. A camera...
Every year as the sun disappears for the winter, the surface waters around Antarctica freeze into a slab of ice 10-feet thick, which effectively doubles the size of the continent. In the summer, the...
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...
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...
Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. The great ice sheets spill out to sea as floating ice-shelves...
Sea stars ( Odontaster validus ) and sea urchins ( Sterechinus neumayeri ) spread over an algae-covered seafloor off the coast of Antarctica. These two species are often found living in association...
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...
Bright colors seem to jump off of this comb jelly, or ctenophore. The rainbow effect appears when light emanates from comb jellies' namesake combs, which are rows of cilia that run up and down their...
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...
Despite the cold and dark environment, soft-bodied animals like anemones abound under the ice. Using their sticky arms, they grab zooplankton, which can be hard to come by during the long winter with...
