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...
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...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving 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...
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...
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...
