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. ...

NASA's aerial survey of polar ice expands its Arctic reach

For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable ...

Arctic sea-ice growth slower than ever

ESA's CryoSat satellite has found that the Arctic has one of the lowest volumes of sea ice of any November, matching record lows in 2011 and 2012. Early winter growth of ice in the Arctic has been about 10% lower than usual.

NASA nears finish line of annual study of changing Antarctic ice

Operation IceBridge, NASA's airborne survey of changes in polar ice, is closing in on the end of its eighth consecutive Antarctic deployment, and will likely tie its 2012 campaign record for the most research flights carried ...

NASA monitors the 'new normal' of sea ice

This year's melt season in the Arctic Ocean and surrounding seas started with a bang, with a record low maximum extent in March and relatively rapid ice loss through May. The melt slowed down in June, however, making it highly ...

NASA science flights target melting Arctic Sea ice

This summer, with sea ice across the Arctic Ocean shrinking to below-average levels, a NASA airborne survey of polar ice just completed its first flights. Its target: aquamarine pools of melt water on the ice surface that ...

Operation IceBridge completes 2016 Arctic spring campaign

Operation IceBridge, NASA's airborne survey of polar ice, ended its eighth spring Arctic campaign on May 21. During their five weeks of operations, mission scientists carried out six research flights over sea ice and ten ...
