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...
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...
To document fragile organisms found in the Arctic , scientist Kevin Raskoff builds special aquaria on the ship to photograph of live critters that have been captured.
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.
Polar bears have evolved to survive in the Arctic with large, oar-like front paws for better swimming, as well as insulating blubber, and two layers of fur for the frigid temperatures. They rely on...
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...
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...
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...
About 2,500 years ago cold climate brought the first Inuit peoples into the Gulf of St. Lawrence, off the coast of Eastern Canada. Early Eskimo groups, known as Groswater Dorset, occupied many sites...
A sea star , Hymenaster pellucidus , brought up from a benthic ROV dive. View the “Under Arctic Ice” photo essay to learn more.
To learn more about the creatures living on the Arctic seafloor, scientists use a variety of tools including this box corer.
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
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...
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...
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...
Special ships called ‘icebreakers’ are needed to access some areas of the ice-covered Arctic Ocean .
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...
This pair of sea butterflies ( Limacina helicina ) flutter not far from the ocean's surface in the Arctic. Sea butterflies are a type of sea snail, but instead of dragging themselves around the...
