| 説明 | Operation IceBridge, NASA’s longest-running aerial survey of polar ice, carried a flight over the northern Antarctic Peninsula on Oct. 16, 2018. During the survey, designed to assess changes in the ice height of several glaciers draining into the Larsen A, B and C embayments, IceBridge senior support scientist Jeremy Harbeck spotted a very sharp-angled tabular iceberg floating among sea ice just off of the Larsen C ice shelf.The rectangular iceberg appeared to be freshly calved from Larsen C, which in July 2017 released the massive A68 iceberg, a chunk of ice about the size of the state of Delaware.The flight originated from Punta Arenas, Chile, as part of a five-week-long IceBridge deployment, which began Oct. 10 and is scheduled to conclude Nov. 18.Credit: NASA/Jeremy Harbeck |
