The MS Arctic Explorer was a ship which sank off St Anthony, Newfoundland, in the Strait of Belle Isle, on 3 July 1981. The 165 foot, 900 tonne icebreaker sank in calm seas in less than 20 minutes leaving 13 crew members dead and 19 survivors drifting in two inflatable liferafts for more than two days until rescued by the Canadian Coast Guard. The ship was chartered to Geophysical Service Inc., a seismic exploration company, which was owned by Texas Instruments at the time she sank.
