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
Canfield ocean during the Great Oxygenation Event. The presence of oxygen in the deep ocean made the formation of BIF impossible, which is seen in ocean sediment records. Conversely, the Canfield Ocean theory postulates that deep ocean water remained anoxic long after the Great Oxidation Event, and he argued that the euxinic conditions in the deep ocean ceased the deposition of BIF in ocean sediments. Euxinic describes anoxic conditions in the presence of hydrogen sulfide. Euxinic ocean conditions, a term describing restricted hydrologic circulation that lead to stagnant or anaerobic conditions, are the likely factor leading to sulfidic oceans. Canfield ocean The
