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...
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 white body of the snow petrel blends in with the stark Antarctic landscape, accentuating the beautiful black eyes and beak of this seabird. They hunt in the sea ice, feeding on krill and fish...
McMurdo Station is the hub of the U.S. Antarctic Program. Since 1955, scientists have been coming to McMurdo primarily in the southern 'summer' months of October to February. Amidst the penguins and...
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...
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 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...
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...
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...
Looking through this iceberg's reflection in the Antarctic water, you can see the iceberg below the surface—some 90% of its total volume. Icebergs are pieces of freshwater ice broken off of glaciers...
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...

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...
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...
“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...
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...
