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).
The Ross Ice Shelf is the main outlet for several major glaciers draining the West Antarctic Ice Sheet, which contains the equivalent of 5 m of sea level rise in its above-sea-level ice." The report added that observations of "iceberg calving" on the Ross Ice Shelf are, in their opinion, unrelated to its stability. [10]
The ice bridge holding the Wilkins Ice Shelf to the Antarctic coastline and Charcot Island was 40 kilometres (25 mi) long but only 500 metres (1,640 ft) wide at its narrowest point – in 1950 it was 100 kilometres (62 mi) It shattered in April 2009 over an area measuring 20.1 by 2.4 kilometres (12.5 by 1.5 mi).
Ice thickness may be measured with ice augers, at required distance intervals or using a ground-penetrating radar (GPR). This is important, since an ice cover can vary as much as 70% in thickness over a few hundred meters, and the minimum ice thickness is used to determine the bearing capacity of the entire ice cover.

The Larsen Ice Shelf is a long ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula [1] from Cape Longing to Smith Peninsula. It is named after Captain Carl Anton Larsen , the master of the Norwegian whaling vessel Jason , who sailed along the ice front as far as 68°10' South during ...
In mid-May 2021, A-76 was, before it broke into three, [1] the world's largest floating iceberg, calved from the Filchner–Ronne Ice Shelf in Antarctica. [ 2 ] [ 3 ] [ 4 ] The new iceberg, effectively a piece of floating ice shelf, detached from the western side of the ice shelf.
