Six existing (yellow) and 32 proposed (red) DART stations
The 'Deep-ocean Assessment and Reporting of Tsunamis' (DART) system is a component of an enhanced
tsunami warning system.
Each DART station consists of a seafloor bottom pressure recording (BPR) package that detects pressure changes caused by tsunamis and a surface
buoy. 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.
Prototype development began in
1995 and the first four DART stations were in place by
2000.
As of 2004, there were six DART stations deployed in the
Pacific; however, due to heightened concerns in the wake of the
2004 Indian Ocean earthquake and its subsequent
tsunamis, plans were announced to deploy an additional 32 DART buoys by mid-
2007.
[1] These would include stations in the
Caribbean and
Atlantic Ocean for the first time.
