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 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. As of January 2025, its area is about 3,500 square kilometres (1,400 sq mi), which makes it the current largest iceberg in the world.
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 ...
<p>Chances are you make it through most days without sparing a thought for Antarctica. At just over 5.4 million square miles, it's a massive chunk of land that is nearly twice the size of ...
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 ...
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
Ice shelves are attached to a large portion of the Antarctic coastline. Their total area is 1,541,700 km 2. [1] Names are also listed in the Scientific Committee on Antarctic Research, Gazetteer. [2] The ice shelf areas are listed below, clockwise, starting in the west of East Antarctica:
Post November 2017, satellite images showed that A-68 was slowly drifting northward, with a widening gap to the main shelf. The gap was approximately five kilometers (3.1 miles) wide and contained a thin layer of loose, floating ice and a cluster of more than 11 'smaller' bergs, one much larger than the others.
