The relatively narrow trough trends east-northeast to west-southwest and has a maximum depth of 7,686 metres (25,217 ft). Within the trough is a slowly spreading north–south ridge which may be the result of an offset or gap of approximately 420 kilometres (260 mi) along the main fault trace.
A bathymetry map of the Mount Dent ocean core complex. The Von Damm vent field is located centrally on the Mid-Cayman Rise between the Oriente and Swan Island transform faults. [ 5 ] The ocean core complex, which the field resides on the eastern side of, is known as Mount Dent and is the most central of the three known on the spreading center.
The team deployed the AUV Autosub6000 to map anomalies and RUV HyBIS to collect video, visually confirming the site named "Beebe" after William Beebe at a depth of 4,960 m (16,270 ft). [ 1 ] [ 6 ] The vent field was further explored by the NOAAS Okeanos Explorer in 2011, R/V Falkor cruise FK008 and R/V Yokosuka cruise YK13-05 in 2013, and ...
The formation of the Cayman Trough produced the last significant tectonic feature on the islands after 39 million years ago, with sinistral strike-slip faults. A structural block produced as a result creates a 5.7 kilometer sinistrally offset contact between the Water Island and Louisenhoj formations.

The American Mediterranean has a surface area of 4.319 million km 2 and an average depth of 2,216 metres (7,270 ft). [1] Its basins include the Mexico Basin, the Cayman Trough, the Yucatan Basin, the Columbian Basin, the Venezuelan basin and the Grenada basin. [3] [1] [4] The American Mediterranean is considered one of the oceanic marginal seas.
The location of the Mid-Cayman Rise. The Mid-Cayman Rise or Mid-Cayman Spreading Center is a relatively short (110 km long) divergent plate boundary in the middle of the Cayman Trough. It forms part of a dominantly transform boundary that is part of the southern margin to the North American Plate. It is an ultra-slow spreading center where the ...
The Gulf is part of the Cayman Trench, one of five deepwater basins in the Caribbean Sea. [29] It contains the open-sea lagoon formed by the Belize Barrier Reef, the Amatique Bay, the Atlantic coast of Guatemala, and the eastern part of the coast of Honduras. [ 29 ]
