Deep ocean minerals not only by its mineral density but cold temperature, cleanliness and trace elements. DOW is present at depths of between 250 and 1500 meters. This deep ocean current moves very slowly under the influence of density and temperature gradients. The high mineral density is attributed to the depth related pressure and the change in temperature from 20 °C+ at the surface to 8 °C at 600 meters depth generates the movement of this layer. "Very deep ocean water" has been discovered in a number of troughs in the Atlantic and Pacific Oceans. Depths can range from 1500 meters to 15
Sigsbee Deep the ACUF Mexico basin with "Sigsbee deep" as an alternate name is given in the NGA database as 25° N 92° W. There are other features with BGN approved names in the region in recognition of this pioneer in deep ocean sounding and commander of the first true bathymetric survey of the Gulf of Mexico conducted while commanding USC&GS "George S. Blake": Sigsbee Deep The Sigsbee Deep (Mexico basin in the U. S. Board on Geographic Names Advisory Committee on Undersea Features (ACUF) Gazetteer), is a roughly triangular basin that is the deepest part of the Gulf of Mexico named
