The
Sparta, a Russian fishing boat which stuck ice while in the Ross Sea in Antarctica was rescued after 12 days by a South Korean ice breaker. The ice tore a hole in the bottom of the Russian boat forcing crew to evacuate in case the boat sank before they could be rescued. Pretty scarey! When I visited Antarctica on the cruise ship
Marco Polo, a small red helicopter, which was kept on one of the decks, would fly ahead and check out the icy waters before the ship ventured in.
