"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...
The world beneath the Arctic ice is magical, but cold. Divers have to tolerate temperatures of 30 degrees Fahrenheit (about -2° Celsius.) To stay warm they wear thermal undergarments and use special...
Polar bears are threatened by the loss of sea ice in the Arctic . They walk for miles on the ice shelves to access different parts of the sea to hunt seals and other food. But as the ice melts as the...
The bowhead whale has a massive, bow-shaped skull to break through thick Arctic ice, and more blubber than any other whale.
Beluga whales are naturally vocal animals. They are often called “ canaries of the sea ” thanks to their wide repertoire of sounds such as whistles, squeals, moos, chirps, and clicks. Some...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
Using a drill, a team removes a chunk from the thick Arctic ice. Small samples are taken from where the ice meets liquid seawater. The ice is then melted for analysis.

Found in the icy waters of the Arctic , Comb Jellies, or ctenophores like this one, of the Aulacoctena genus, are poorly known animals. With extremely fragile bodies, they are difficult to capture...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
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...

In the icy waters of the Arctic , a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost...
Geologist Charles Paull (Monterey Bay Aquarium Research Institute) investigates geologic features similar to pingos (Earth covered ice mounds found in the Arctic) on the Arctic Ocean floor where...
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...
Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
