Alaskan mountains seen from high altitude aboard the NASA P-3B during the IceBridge transit flight from Thule to Fairbanks on March 21, 2013.

NASA's Operation IceBridge scientists have begun another season of research activity over Arctic ice sheets and sea ice with the first of a series of science flights from Greenland completed on Wednesday.

View of Sheldon Glacier with Mount Barre in the background, seen from Ryder Bay near Rothera Research Station, Adelaide Island, Antarctica. A new NASA/British Antarctic Survey study examines why Antarctic sea ice cover has increased under the effects of climate change over the past two decades.

Set against a star-studded backdrop and a splash of the Milky Way, the green glow of an auroral curtain pervades the permanently dark winter skies of the South Pole.

The extent of the sea ice covering the Arctic Ocean has shrunk. According to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo., the amount is the smallest size ever observed in the three decades since consistent satellite observations of the polar cap began.

I recently had a chance to ask Dr. Alexander Kumar a few questions about his experiences in Antarctica - and elsewhere - as they related to space exploration - and exploration in general.

An unusually strong storm formed off the coast of Alaska on August 5 and tracked into the center of the Arctic Ocean, where it slowly dissipated over the next several days.

Polar View (Norway) has carried out this GSP study comparing the needs of Arctic stakeholders (as articulated in policies and strategies) with the contribution different types of satellite technologies can make to meet current and future requirements.

For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its 2-mile-thick (3.2-kilometer) center, experienced some degree of melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists.

Fifteen orbits of the recently launched Suomi NPP satellite provided the VIIRS instrument enough time (and longitude) to gather the pixels for this synthesized view of Earth showing the Arctic, Europe, and Asia.

Marking another remarkable collaborative effort, ESA and NASA met up over the Arctic Ocean this week to perform some carefully coordinated flights directly under CryoSat orbiting above. The data gathered help ensure the accuracy of ESA's ice mission.

CryoSatApp: Ice Data at Your Fingertips, ESA

"Discover ESA's ice mission, track it in real time and obtain the latest measurements with the new CryoSat application. CryoSat is measuring the thickness of polar sea ice and monitoring changes in the ice sheets that blanket Greenland and Antarctica. The CryoSat iPhone and iPad application - or CryoSatApp - is now available at Apple's App Store. "
