The evolving ice of Antarctica

NASA’s Operation IceBridge has been studying how polar ice has evolved over the past eight years and conducted a set of 12-hour research flights over West Antarctica at the start of the melt season. Researchers have used the IceBridge data to observe that the West Antarctic Ice Sheet may be in a state of irreversible decline directly contributing to rising sea levels. NASA and University of California, Irvine (UCI) researchers have recently detected the speediest ongoing Western Antarctica glacial retreat rates ever observed.

  1. The developing ice of Antarctica

  3. A segment of ice close to the shore of West Antarctica is seen from a window of a NASA Operation IceBridge plane on Oct. 31, in-flight over Antarctica. (Mario Tama/Getty Images)

  4. A perspective of an enormous break in the Antarctic Peninsula's Larsen C ice retire on Nov. 10. Ice racks are the skimming parts of ice streams and ice sheets, and they brace the grounded ice behind them; when ice racks fall, the ice behind quickens toward the sea, where it then adds to ocean level ascent. The IceBridge researchers measured the Larsen C crack to be around 70 miles in length, more than 300 feet wide and about 33% of a mile profound. It will deliver an icy mass generally the measure of the condition of Delaware. (Maria-Jose Vinas/NASA by means of AFP/Getty Images)
