The Explorer was reported listing in the Bransfield Strait after the 154 aboard were taken aboard a Norwegian liner and transported to nearby King George Island.

The New York Times said reports from rescue ships on the scene indicated no injuries, although the Explorer was listing 40 degrees, which a spokesman for Toronto-based tour operator G.A.P. Adventures said was "not a good sign." A distress call was issued Thursday from the 40-year-old ship Thursday, which was designed for polar operations and had sailed from Argentina on Nov. 11.
