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 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 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. [1]
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 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 water is then either filtered (sand or cartridge filter,) or settled (lamella clarifier or weir tank) prior to discharge. Chemical sediment control is currently used on some construction sites around the United States and Europe, typically larger sites where there is a high potential for damage to nearby streams. [ 3 ]
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
