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...
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 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...
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...
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...
"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...
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...
Humpback whales ( Megaptera novaengliae ) can be found in Antarctic waters during the spring and summer in the Southern hemisphere, where they gorge on their main food source: tiny krill. How do they...
Did you know that over 17,000 species thrive in the deep sea where no light penetrates the ocean waves? Or that an old restaurant menu can teach us about the history of fish populations? Or that...
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...
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...
“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...
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...
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...
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...
At the ends of the Earth, life thrives despite extreme conditions. In the Arctic and Southern Oceans, organisms have evolved adaptations to cope with year-round cold and six months of darkness. But...
The New Zealand Sub-Antarctic Islands site was inscribed on the World Heritage List in 1998. The islands are particularly notable for the abundance and diversity of nesting pelagic seabirds and...
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...
