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...
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...
Lanceola clausi , the bull-dog amphipod , another rare deep-water species captured below 1000 meters (3281 feet) with the multinet . View the “Under Arctic Ice” photo essay to learn more.
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...
A sea star , Hymenaster pellucidus , brought up from a benthic ROV dive. View the “Under Arctic Ice” photo essay to learn more.
Even if you aren't a hardcore birder, chances are you have some hidden love for penguins. These flightless birds have captured our hearts through countless movies, beautiful images and their adorable...
"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...
Looking through this iceberg's reflection in the Antarctic water, you can see the iceberg below the surface—some 90% of its total volume. Icebergs are pieces of freshwater ice broken off of glaciers...
The bowhead whale has a massive, bow-shaped skull to break through thick Arctic ice, and more blubber than any other whale.
An emperor penguin chick ( Aptenodytes forsteri ) huddles under its mother's legs to keep warm in the long Antarctic winter. Learn more about research on emperor penguins and other Antarctic...
Hoping to hear bowhead whales , NOAA marine mammal scientist Sue Moore listens to real-time sounds from an underwater hydrophone.
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...
Bivalves brought up in a box corer from the deep Arctic seafloor.
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...
Several species of amphipod like this one, Gammarus wilkitzkii , live permanently within Arctic sea ice . These animals are endemic, meaning they only live here. They acclimate to a wide range of...
The National Ice Center’s work is focused on ensuring safe and efficient navigation, but it also supports scientific research and provides crucial information used by scientists to better monitor and...
The crabeater seal ( Lobodon carcinophaga ) is found on the ice of Antarctica, but surprisingly they don't eat crabs! The seals primarily eat krill, tiny crustaceans that play a large part in the...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
