The Larsen B ice shelf is located in the northwest part of the Weddell Sea, along the east coast of the Antarctic Peninsula from Cape Longing to Hearst Island. It is believed that the entire area weighed 500 billion tonnes. Larsen B was stable for at least 10,000 years, essentially the entire Holocene period since the last glacial period. From January 2002 to March 2002, the Larsen B ice shelf partially collapsed. The shattering of Larsen B dumped more ice into the Southern Ocean than all of the previous half century's iceberg combined.
