羅斯冰架
A common event of previously unseen dimensions occurred on the Ross Ice Shelf in 2000 that wreaked havoc at McMurdo Sound more than five years later. The long Iceberg B-15, the largest ever seen at the time, broke off from the Ross Ice Shelf in March 2000 (Antarctic Climate &amp; Ecosystems: Cooperative Research Center). Then, on 27 October 2005, B-15 suddenly broke up.
