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 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).
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]
Wilkins Sound is a seaway in Antarctica that is largely occupied by the Wilkins Ice Shelf. It is located on the southwest side of the Antarctic Peninsula between the concave western coastline of Alexander Island and the shores of Charcot Island and Latady Island farther to the west.

Sea ice was 2 m (6.6 ft) thick with a water depth of 150–300 m (490–980 ft) below. Four overlapping drill cores at three sites reflect in excellent quality the geological history and glaciation of the Antarctic during the last 34 million years.
