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...
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...
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...
