South Sandwich Trench
The South Sandwich Trench is a deep arcuate trench in the South Atlantic Ocean lying 100 km to the east of the South Sandwich Islands. The trench is produced by the subduction of the southernmost portion of the South American Plate beneath the small South Sandwich Plate. The South Sandwich Islands constitute a volcanic island arc which results from this active subduction. Mount Belinda on Montagu Island is an active volcano.
The southernmost portion of the South Sandwich Trench reaches south of 60°S and therefore into the Southern Ocean, thereby containing the maximum depth of that Ocean at 60°00'S, 024°W, with a depth of 7,235 meters.
