ARA BahÃÂa ParaÃÂso was an Argentine Navy auxiliary ship that sank in 1989, from Palmer Station at Arthur Harbor, Antarctica, resulting in a oil spill.
BahÃÂa ParaÃÂso was ordered by the Argentine Navy on 27 February 1979 as a supply ship for use in Antarctic waters. The ship was launched from the Argentine shipyard Astilleros PrÃÂncipe y Menghi SA on 3 July 1980, entering service on 3 December 1981, with the pennant number Q 6.

The ship's holds had a capacity of dry cargo, with an additional refrigerated storage, together with 1200 tons of cargo fuel. A flight deck and hangar for two helicopters was fitted. The ship had a crew of 124, and could carry 84 civilian passengers, who could be replaced by 252 troops.
The ship operated as a naval auxiliary vessel from 1981 to 1986 and served in the Falklands War as a troop transport as well as a hospital ship. It was involved in transporting troops to Leith Harbour prior to the Invasion of South Georgia.
After the war it reverted to an Antarctic supply ship for the Navy with occasional tourists on board. It was on a resupply trip with tourists to Antarctica on January 28, 1989 when it struck rock and sank off Anvers Island. Passengers and crew were rescued by the Spanish Navy oceanographic research vessel Las Palmas and the Chilean Navy tug Cruz de Forward.
The resultant oil spill of about 200,000 gallons of diesel and jet fuel constitutes the largest oil spill in Antartica. Chilean Coast Guard Tender Yelcho arrived February 6 to begin clean up operations.
