The "Endless Sea" is trapped in the ice and is spilling fuel. There is no hope of containing damage until October this year, due to the long South Pole winter.
Huffington Post reports that the Brazilian-owned ship capsized and sank in 12 meters of water last month, close to where Chile and Brazil hold navy bases. While the crew was rescued without injury, poor weather prevented them from diving below to check the damage until Wednesday this week.
The ship was carring some 8,000 litres of oil. However, Veronica Vallejos of the Chilean Antarctic Institute told AP that the extent of the spill is currently known.
