Arctic sea ice thinning faster than expected

Sea ice in the coastal regions of the Arctic may be thinning up to twice as fast as previously thought, according to a new modelling study led by UCL researchers.

Geographers draw up an ice thickness map of Svalbard

Global sea levels are rising constantly. One factor contributing to this rise is the melting of the glaciers. Although the surface area of the glaciers has been well mapped, there is often no information regarding their thickness, ...

With thick ice gone, Arctic sea ice changes more slowly

The Arctic Ocean's blanket of sea ice has changed since 1958 from predominantly older, thicker ice to mostly younger, thinner ice, according to new research published by NASA scientist Ron Kwok of the Jet Propulsion Laboratory ...

NASA renews focus on Earth's frozen regions

In 2018, NASA will intensify its focus on one of the most critical but remote parts of our changing planet with the launch of two new satellite missions and an array of airborne campaigns.

NASA begins latest airborne Arctic ice survey

An unusual hole in the sea ice cover over the Arctic Ocean and unexplored areas of the bedrock beneath the Greenland Ice Sheet are among the targets for this year's mapping of Arctic ice conditions by NASA's Operation IceBridge ...

NASA scientists seek to improve sea ice predictions

Sea ice in the Arctic Ocean is in a downward spiral, with summer minimum extents about 40 percent smaller than in the 1980s. But predicting how the sea ice is going to behave in a particular year is tricky: There are still ...

Solving the mystery of the Arctic's green ice

In 2011, researchers observed something that should be impossible—a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. ...
