“In late November, land-locked polar bears gather along the Hudson Bay to await the formation of Arctic ice so they can return to their seal-hunting grounds for the winter.” -- Nature's Best...
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...
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...
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...
Dryodora glandiformis is a ctenophore found in Arctic and Northern European waters, bearing a pair of long and lovely 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...
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...
"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...
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...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
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...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
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...
Bottom trawl treasures from the shallow Chukchi Seafloor near the Canada Basin: sea stars , brittle stars , clams, some snails and crabs. View the “Under Arctic Ice ” photo essay to learn more.
The Boreoatlantic armhook squid ( Gonatus fabricii ) is named for its fabulous (but dangerous) suckers. While most squids have just two rows of suckers lining each arm, armhook squids have four—and...
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...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
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...
