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 Assessment and Reporting of Tsunamis Deep-ocean Assessment and Reporting of Tsunamis The Deep-ocean Assessment and Reporting of Tsunamis (officially abbreviated and trademarked as DART) system is a component of an enhanced tsunami warning system. Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects pressure changes caused by tsunamis. The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's National Data Buoy Center, and NOAA's Pacific Marine Environmental Laboratory (PMEL).
