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 ...
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 ...
The split of the A38-B iceberg is recorded in this series of images. The iceberg was originally part of the massive A-38 iceberg, which broke from the Ronne Ice Shelf in Antarctica [3] B-15A: 6,400 2002 Northern edge of Iceberg B-15A in the Ross Sea, Antarctica, 29 January 2002: A-68: 5,800 175 50 2017 Calving crack in the Larsen C ice shelf [2 ...
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 world’s largest iceberg is on the move again, drifting through the Southern Ocean after months stuck spinning on the same spot, scientists from the British Antarctic Survey (BAS) have said.
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.
The Patagonian glacier drops large amounts of ice about every four years. The last rupture was in 2012. Partial breaks occurred in February, indicating a large collapse could happen soon.
This road typically runs over land and over frozen lakes, rivers, swamps, and sea ice. [1] [2] Segments of a winter road that cross an expanse of floating ice are also referred to as an ice road or an ice bridge. [1] The foundations underlying over-land segments is most often native soil or muskeg frozen to a given depth, and locally, bedrock.
