Less Ice Equals More Seal Strandings on US Coast

Harp seals mate and rear their young on the sea ice off the east coast of Canada in the spring and move north as the weather warms. But increasing numbers of seals are ending up stranded along the U.S. East Coast, as far south as the Carolinas, far away from where they should be at this time of year Full story

How Eerie Sea Ice 'Brinicles' Form

What's cooler than being cool? Brine-cold. When salt-rich water leaks out of sea ice, it sinks into the sea and can occasionally create an eerie finger of ice called a brinicle. New research explains how these strange fingers of ice form and how the salty water within sea ice could have been a prime Full story

Sea Ice Loss Could Alter Arctic Air Chemistry

Over the past 30 years, the Arctic has warmed more than any other place on the planet, and that warming and the resulting melt of the region's sea ice presents a number of potential adverse effects, from impacts on weather systems to the decline in the habitats of native species. Full story

Say Goodbye to Arctic Summer Ice

By the time today's babies graduate college, there's a very good chance they could celebrate with a cruise across the North Pole. Full story

Saunders Island and Wolstenholme Fjord with Kap Atholl in the background is shown in this picture taken during an Operation IceBridge survey flight in April 2013. Sea ice coverage in the fjord ranges from thicker, white ice seen in the background, to thinner grease ice and leads showing open ocean w

Sea water off the east coast of Greenland looked a bit like marbled paper in October 2012. The shifting swirls of white were sea ice, as observed by the Moderate Resolution Imaging Spectroradiometer on NASA's Aqua satellite on October 17, 2012. In fact, this ice moved discernibly between October 16
