A research ship has arrived to help rescue a Russian fishing vessel that struck ice off of Antarctica 10 days ago, officials in New Zealand said. The Sparta hit underwater ice December 16, leaving a one-foot hole in the ships hull. The ship has been stranded in an area about 2,000 miles from New Zealand, where the ice has been so thick that rescue ships have had difficulty getting close. Since becoming stuck, 32 crew members have been working with rescuers to try to patch up the hole to keep the ship from sinking. They had been given tools dropped by a New Zealand Air Force plane, helping them pump out freezing water that was rushing into the ship. But it has been difficult for the crew to both patch up the hole and pump out water, an official said.
