NASA to fly parallel science campaigns at both poles

For the first time in its seven years of flights, NASA's Operation IceBridge, an airborne survey of changes in Earth's polar ice, is conducting overlapping campaigns in Antarctica and the Arctic. Since 2009, IceBridge has ...

Glaciers melt faster than ever

The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years. Together with its National Correspondents in more than 30 countries, the ...

NASA contributes to first global review of Arctic marine mammals

Many human communities want answers about the current status and future of Arctic marine mammals, including scientists who dedicate their lives to study them and indigenous people whose traditional ways of subsistence are ...

2014 Arctic sea ice minimum sixth lowest on record (Update)

Arctic sea ice coverage continued its below-average trend this year as the ice declined to its annual minimum on Sept. 17, according to the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, ...

Melt ponds shine in NASA laser altimeter flight images

Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal clear pools.

Charting Icelandic glacier dynamics

Mark Simons, professor of geophysics at Caltech, along with graduate student Brent Minchew, recently logged over 40 hours of flight time mapping the surface of Iceland's glaciers. Flying over two comparatively small ice caps, ...
