Deep-ocean Assessment and Reporting of Tsunamis completed in 2008 totaling 39 stations in the Pacific Ocean, Atlantic Ocean, and Caribbean Sea. The international community has also taken an interest in DART buoys and as of 2009 Australia, Chile, Indonesia and Thailand have deployed DART buoys to use as part of each country's tsunami warning system. In the 2018 budget justification for NOAA, the Trump administration proposed eliminating the DART system as part of a 56% cut to the tsunami warning program. Deep-ocean Assessment and Reporting of Tsunami buoy systems are made up of three parts. There is a pressure recorder anchored to the bottom of the
Deep ocean minerals are three distinctly different layers of ocean water - Surface Sea Water, Deep Ocean Water (DOW) and Very Deep Ocean Water. Each layer remains separate and autonomous from the others, moving at different speeds and directions from different kinetic forces and having different temperatures, densities and life form status. "The surface sea water layer" is influenced by sunlight penetration and circulates rapidly in unison with the seasons and wind patterns to a depth of 250 meters. It supports micro and animal life. "The middle layer is DOW" where the water is free of sunlight and life forms. It is characterized
