The deep in the South Sandwich Trench surveyed by the German Meteor expedition was Meteor Deep.
The German research vessel Meteor identified the trench’s deepest point during the 1925–1927 German Atlantic Expedition. The expedition used early echo-sounding technology, a major advance in measuring deep-ocean relief, and recorded the feature at roughly 8,050 metres.
Meteor Deep is named after the survey ship, not after a meteorological event. Modern multibeam sonar mapping during the 2019 Five Deeps Expedition measured a deeper point in the same trench at about 8,266 metres, while retaining the established name Meteor Deep.
A common mix-up is Brownson Deep, also called the Milwaukee Deep, which is associated with the Puerto Rico Trench. The South Sandwich Trench lies east of the South Sandwich Islands and is formed where the South American Plate descends beneath the South Sandwich Plate.
