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...
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...
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...
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...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
It’s confirmed: both Antarctica and Greenland are losing ice —around 350 billion tons each year—and, as a result, sea level has risen 11.1 millimeters worldwide since 1992. This photo shows a...
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.
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...
From the open ocean to coastal tidepools, from the fantastic to the familiar, a mosaic of marine habitats provides homes, feeding and spawning grounds, and seasonal destinations for ocean species...
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...
“As we motored around Paulet Island in a Zodiac boat, these two curious penguins waddled across an iceberg to get a closer look at us.” -- Nature's Best photographer, Phillip Colla . See more...
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...
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...
Lying on the ice with a few friends is not an unusual way to spend time for walruses, who tend to be sociable animals. Their groups can range from tens to thousands. Each individual herd has a...
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...
Bivalves brought up in a box corer from the deep Arctic seafloor.
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...
