Antarctic Sound

From Wikipedia, the free encyclopedia

Antarctic Sound (63°20′S, 056°45′W) is a body of water about 48 km (30 mi) long and from 11 to 19 km (7 to 12 mi) wide, separating the Joinville Island group from the northeast end of Antarctic Peninsula.

The sound was named by the Swedish Antarctic Expedition under Otto Nordenskiöld for the expedition ship Antarctic which, in 1902 under the command of Carl Anton Larsen, was the first vessel to navigate it.
