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 ...
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 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.
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.
These animations show the motion of ice in Antarctica. Velocity map of Antarctica. Ice streams can be seen with increasing speeds (blue-yellow-white) flowing toward the coast.

A spokesman from the British Antarctic Survey stated that the iceberg could become stuck for a number of years, causing disruption to wildlife and the local fishing industry. [16] On 9 December 2020, the Royal Air Force released video footage of A-68A, 150 km off South Georgia. The RAF conducted reconnaissance flights over the iceberg on 18 ...
