The Sargasso Sea (/ s ɑːr ˈ ɡ æ s oʊ /) is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre. [1] Unlike all other regions called seas, it has no land boundaries. [2] [3] It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and often calm blue water. [1]
The Caribbean remained like this for most of the Cenozoic until the Holocene when rising water levels of the oceans restored communication with the Atlantic Ocean. The Caribbean's floor is composed of sub-oceanic sediments of deep red clay in the deep basins and troughs.
The Gulf's open sea experiences the Caribbean Current and a quasi-permanent cyclonic eddy generated in the southwest corner of the Cayman Tranch. [ 44 ] [ 45 ] The latter is centred at about 19°N 86°W, generating a sea surface height anomaly of negative 7.9 inches (0.2 m), with peripheral current velocities of 7.9 to 15.8 inches per second (0 ...
The sediment itself is often composed of limestone, which forms readily in shallow, warm, calm waters. While siliciclastic and carbonaceous sediments can coexist, shallow marine environments can also contain only one or the other. Shallow water marine sediment primarily features larger grain sizes because smaller grains have washed out to ...
[7] [8] [9] In January 2012, the researchers announced that water exits the vents at a temperature possibly exceeding 450 °C (842 °F), making them among the hottest known undersea vents. They also announced the discovery of new species, including an eyeless shrimp with a light-sensing organ on its back.
