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
Diamantina Deep Diamantina Deep The Diamantina Deep is located in the Diamantina Trench southwest of Perth, Western Australia. The Diamantina Trench is in the eastern part of the larger Diamantina Fracture Zone, which stretches from the Ninety East Ridge to the Naturaliste Plateau, off the lower part of Southwest Australia. It is one of the deepest points (surpassed by the Sunda Trench) in the Indian Ocean at . It is located about west-southwest of Perth at . A survey in 1961 by the Australian oceanographic survey ship confirmed the bathymetry and conducted a scientific survey. The trench (and the Fracture Zone) was
