Operation IceBridge (OIB) was a NASA mission to monitor changes in polar ice by utilizing airborne platforms to bridge the observational gap between the ICESat and ICESat-2 satellite missions. The program, which ran from 2009 to 2019, employed various aircraft equipped with advanced instruments to measure ice elevation, thickness, and ...
A23a's course mapped by the NASA Earth Observatory [1]. A23a is a large tabular iceberg which calved from the Filchner–Ronne Ice Shelf in 1986. It was stuck on the sea bed for many years but then started moving in 2020.
March 2017 became the sixth month in a row to set a record for the lowest sea ice extent, according to the National Snow and Ice Data Center (NSIDC). Operation Icebridge: NASA photos capture ...
Northern edge of Iceberg B-15A in the Ross Sea, Antarctica, 29 January 2001. Iceberg B-15 was the largest recorded iceberg by area. [Note 1] It measured around 295 by 37 kilometres (159 by 20 nautical miles), with a surface area of 11,000 square kilometres (3,200 square nautical miles), about the size of the island of Jamaica.
The Antarctic Ice Sheet is drained to the sea by several ice streams. The largest in East Antarctica is Lambert Glacier.In West Antarctica the large Pine Island and Thwaites Glaciers are currently the most out of balance, with a total net mass loss of 85 gigatonnes (84 billion long tons; 94 billion short tons) per year measured in 2006.

The polynya forms initially when first-year pack ice is driven away from the coast, which leaves an area of open water within which new ice is formed. This new ice is then also herded downwind toward the first-year pack ice. When it reaches the pack ice, the new ice is consolidated onto the pack ice. This process continues over time.
