The Cayman Trough (also known as the Cayman Trench, Bartlett Deep and Bartlett Trough) is a complex transform fault zone pull-apart basin which contains a small spreading ridge, the Mid-Cayman Rise, on the floor of the western Caribbean Sea between Jamaica and the Cayman Islands. [1]
The Beebe vent field was initially detected in October 2009 by CTD, Eh, and optical backscatter anomalies in the water column above the Mid-Cayman Rise aboard the R/V Cape Hatteras. [ 3 ] [ 4 ] The team deployed HROV Nereus to conduct surveys which identified a double hydrothermal plume at 3,900 metres (12,800 ft) and 4,250 m (13,940 ft) deep ...
The Von Damm Hydrothermal Field is a field of hydrothermal vents located just south of Grand Cayman in the Caribbean, on the Mid-Cayman Rise in the Cayman Trough. It is approximately 24 kilometres (15 mi) south of the Beebe Vent Field. The vent field is named in commemoration of geochemical oceanographer Karen Von Damm, who died in 2008. [1]
The Cayman Ridge is an undersea mountain range on the northern margin of the Cayman Trough in the Caribbean Sea. It extends from the Sierra Maestra in the east to the Misteriosa Bank and Rosario Bank in the west, a distance of about 1,500 km (930 mi). The Cayman Ridge also includes the Cayman Islands. [1]
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 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 ...
A vent site in the Cayman Trough named Beebe, which is the world's deepest known hydrothermal site at ~5,000 m (16,000 ft) below sea level, has shown sustained supercritical venting at 401 °C (754 °F) and 2.3 wt% NaCl. [11]
The Cayman Islands are a British dependency and island country. It is a three-island archipelago in the Caribbean Sea , consisting of Grand Cayman , Cayman Brac , and Little Cayman . Georgetown, the capital of the Cayman Islands is 438 km (272 mi) south of Havana , Cuba , [ 1 ] and 504 km (313 mi) northwest of Kingston, Jamaica , [ 2 ...
