To ensure early detection of tsunamis and to acquire data critical to real-time forecasts, NOAA has placed Deep-ocean Assessment and Reporting of Tsunami (DART®) stations at sites in regions with a history of generating destructive tsunamis. NOAA completed the original 6-buoy operational array (map of original six stations) in 2001 and expanded to ...
DART® systems consist of an anchored seafloor bottom pressure recorder (BPR) and a companion moored surface buoy for real-time communications (Gonzalez et al., 1998). An acoustic link transmits data from the BPR on the seafloor to the surface buoy. The BPR collects temperature and pressure at 15-second intervals. The pressure values are corrected f...

Deep-ocean Assessment and Reporting of Tsunamis (DART) is a component of an enhanced tsunami warning system. By logging changes in seafloor temperature and pressure, and transmitting the data via a surface buoy to a ground station by satellite, DART enables instant, accurate tsunami forecasts.
A system overview for the National Data Buoy Center's Deep-ocean Assessment and Reporting of Tsunamis (DART®) stations. DART® stations report water-column height and are used for validating whether subsurface earthquakes have generated tsunamis.
DART® technology was developed to detect and measure tsunami waves in the deep ocean for the purpose of increasing scientific understanding of their generation and propagation, and for improving forecasts of their impact along vulnerable coastlines.
DART® (Deep-ocean Assessment and Reporting of Tsunamis) is a network of buoys that measure and report sea level changes in the ocean. DART® helps improve tsunami forecasting and warning by providing data to Tsunami Warning Centers.
Jun 12, 2023 · Recognizing the importance of detecting tsunamis in real time as they travel across the open ocean, NOAA developed a tsunami measurement system called Deep-ocean Assessment and Reporting of Tsunami (DART).
