Operation IceBridge resumes Antarctic flights

(Phys.org)—Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica. Now in its fourth year, IceBridge's return ...

Glaciers cracking in the presence of carbon dioxide

(Phys.org)—The well-documented presence of excessive levels of carbon dioxide (CO2) in our atmosphere is causing global temperatures to rise and glaciers and ice caps to melt. New research, published today in the Journal ...

West Antarctic ice shelves tearing apart at the seams

A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an ...

Image: Crack discovered in Pine Island Glacier

(PhysOrg.com) -- In mid-October 2011, NASA scientists working in Antarctica discovered a massive crack across the Pine Island Glacier, a major ice stream that drains the West Antarctic Ice Sheet. Extending for 19 miles (30 ...

Tropical sea temperatures influence melting in Antarctica

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according ...

International team to drill beneath massive antarctic ice shelf

(PhysOrg.com) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in ...

Watching the birth of an iceberg

(PhysOrg.com) -- After discovering an emerging crack that cuts across the floating ice shelf of Pine Island Glacier in Antarctica, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed ...
