The M/S Explorer cruise ship, operated by GAP Adventures of Canada, is seen offshore of a Gentoo penguin colony on Cuverville Island, during a tourist expedition in this February 2005 file photo. The Explorer's more than 150 passengers and crew escaped unhurt after the ship hit an iceberg and listed off King George Island on November 23, 2007, forcing them to escape in lifeboats before a Norwegian passenger boat in the area picked them up, the company running the ship said.
