Scientists are excited when they discover an animal where they had never seen it before. This eelpout fish, Lycodes adolfi, was seen on the Pacific side of the Arctic in 2009. Previously, scientists...
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...
Narwhals ( Monodon monoceros ) are a type of toothed whale, best known for their long unicorn-like tusk. The tusk is normally found on male narwhals and is actually a tooth. Narwhals usually live in...
New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic Ocean . By collecting organisms and mapping the seafloor, researchers can...
This copepod Calanus hyperboreus (up to 7mm in length) lives in the Arctic , usually within 500 meters of the surface. To survive the cold Arctic winters, Calanus hyperboreus builds up dense fat (...
To people living in warm climates, all ice looks the same. But if you live day-in and day-out on sea ice, like the Inupiaq people of Alaska, you would find that there are many kinds of ice, all...
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.

The bowhead whale has a massive, bow-shaped skull to break through thick Arctic ice, and more blubber than any other whale.
Chapter 3: Fragile Fauna Jelly Critters Grade Level: 5-6 Focus: Life Science- Gelatinous zooplankton in the Canada Basin Description: In this activity, students will be able to compare and contrast...
Scientists document a direct relationship between the extent of sea ice and polar bear survival. Future projected reductions in the extent of annual sea-ice due to global warming may result in the...
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...
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...
Light refracts off the comb-rows of the Mertensia ovum , a ctenophore , producing stripes of rainbow colors . The jelly eats copepods and small crustaceans that become stuck to its sticky tentacles...
Using an ROV (Remotely-Operated Vehicle) equipped with a high-definition video camera, scientists can observe the life that flourishes beneath the Arctic ice . On this expedition, they discovered...
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...
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...
