Travel to the ends of the earth—literally—and discover the polar ocean basins. Both the Arctic Ocean and the Southern Ocean...
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...
The Arctic Tern could really be called the Arctic-Antarctic Tern. It has the longest migration of all birds, flying from breeding grounds near the North Pole to wintering grounds off Antarctica. That...
Sea ice is typically viewed as the domain of physical and natural scientists, the oceanographers, marine biologists, climate modelers, and navigators of the world. It is easy to forget another...
Found in Arctic waters, this rare deep-water species of larvacean , Oikopleura gorskyi , eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves...
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...
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...
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...
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...
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...
In the spring of 2011, a research crew from Oceana spent two months in the brackish Baltic Sea . The Baltic faces challenges from pollution, algae blooms, over fishing, and invasive species. Oceana...

A dive tender monitors the line connected to ice divers studying creatures living on the underside of the Arctic Sea ice .
This species of amphipod , Eusirus holmii , was found both at the surface of Arctic waters and as deep as 2000 meters (6562 feet). Researchers have found that while the amphipod inhabits the sea ice...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
Ice divers use a quadrat to study the density of creatures living on the underside of Arctic ice floes. A quadrat is a standardized square used to take sample measurements that allow researchers to...
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...
It takes special equipment and many warm layers of clothing to dive safely beneath Arctic sea ice . Ice divers look for holes in a melt pond in order to enter the frigid waters.
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...
