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...
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...
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...
During the winter and spring months, tagged fur seals migrate thousands of miles in open water. Scientists are watching this species closely in order to determine the mystery of its population...

The threat that climate change poses to polar bears has received a lot of attention, but they are not the only Arctic species at risk. Ice-loving seals, such as harp, hooded and ringed seals, are...
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...
Arctic scientists study a range of marine animals – from large species like polar bears to the microscopic, like phytoplankton. The amount of phytoplankton at different depths can tell us about the...

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...
