The collier Shen Neng 1 has been refloated and removed from Australia’s Great Barrier Reef where it grounded ten days ago.   In its wake it has left severe damage to the reef.  As reported by the BBC:  The Australian authorities have said a Chinese bulk carrier which ran aground off Queensland has caused widespread damage to the famed Great Barrier Reef. The cleanup is likely to be the biggest operation ever undertaken there. Toxic paint from the ship’s hull is reported to have killed coral in a swath over a kilometer long.  Oil spilled from the ship’s bunker tanks has washed up at a nature sanctuary threatening birds and baby turtles.  The Chinese owner of the ship has apologized while the government of Australia has arrested two of the ship’s senior officers.
