Seasons in the Ross Sea are marked by ice freezing and melting, and these processes mix the seawater and redistribute salt and nutrients. The influx of nutrients cause phytoplankton to bloom, forming...
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...
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...
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...
The dark seafloor beneath the ice is covered with sea stars, urchins and ribbon worms looking for their next meal, which can come from sponges, dead animals that float to the sea floor, or even other...
An emperor penguin chick ( Aptenodytes forsteri ) huddles under its mother's legs to keep warm in the long Antarctic winter. Learn more about research on emperor penguins and other Antarctic...
“As we motored around Paulet Island in a Zodiac boat, these two curious penguins waddled across an iceberg to get a closer look at us.” -- Nature's Best photographer, Phillip Colla . See more...
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...
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 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...
At the Poles, Life Thrives Located beside the Shores and Shallows gallery (which highlights different kinds of coastal ecosystems around the world), the Poles area will take you to the ends of 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...
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...
"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...
This shadowy fish, Trematomus bernacchii , is well adapted to the ice-cold water of the Antarctic: its blood comes equipped with natural antifreeze. This is a necessary adaptation because the...
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...
