Scientists know the Greenland shark ( Somniosus microcephalus ) moves slowly in the Arctic's cold water. They also know that parasites attack the shark's eyes. But much about this animal remains a...
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...
Research at Hare Harbor in Quebec, Canada has revealed important clues about the connections between the Inuit peoples of Northern Canada and the Basque whalers of Spain and France. Excavations at...
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...
To learn more about the creatures living on the Arctic seafloor, scientists use a variety of tools including this box corer.
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...
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...
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...
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...
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...
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...
A 2011 excavation led by the Arctic Studies Center uncovered this fragment of decorated European stoneware called a bellarmine jug. Uncovering this fragment, that was likely manufactured in the 15th...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
The Arctic Studies Center's excavation site map of Hare Harbor maps some of the community's excavated structures that archeologists have unearthed. An Inuit house, blacksmith shop, and cookhouse are...
Dryodora glandiformis is a ctenophore found in Arctic and Northern European waters, bearing a pair of long and lovely tentacles.
Walruses use sea ice as platforms on which to nurse their young and launch their dives for clams and other bottom-dwellers. Each spring, walruses move northward to stay close to these perches as ice...
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...
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...
