The Antarctic Sound is a body of water about 30 nautical miles (56 km; 35 mi) long and from 7 to 12 nautical miles (13 to 22 km; 8 to 14 mi) wide, separating the Joinville Island group from the northeast end of the Antarctic Peninsula. The sound was named by the Swedish Antarctic Expedition under Otto Nordenskjöld for the expedition ship Antarctic which in 1902, under the command of Carl Anton Larsen, was the first vessel to navigate it. Since 2005 cruise ships have been visiting the area.
