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
Titans of the Deep creatures seen and filmed at that depth for the first time. Titans of the Deep Titans of the Deep is a 1938 film inspired by the early 1930s deep sea dives made by William Beebe and Otis Barton. Beebe and Barton were the first to set ocean depth records in a device invented by Barton. The film was written by Les Adams. It was somewhat intended as a documentary but was often sold and advertised as an exploitation/horror picture. Prominent scientists Dr. William Beebe and Otis Barton, using the Bathysphere invented by Barton, descend several thousand feet to the ocean
