Operational Performance of the Second Generation Deep-Ocean Assessment and Reporting of Tsunamis (DART (trademark) II)

Abstract

In March 2005, the National Oceanic and Atmospheric Administration (NOAA) completed the transition from research to operations of the second generation of the Deep-ocean Assessment and Reporting of Tsunamis (DART(TM) II). DART(TM) II systems are a part of NOAA's Tsunami Program, which is part of a cooperative effort to save lives and protect property through hazard assessment, warning guidance, mitigation, research capabilities, and international coordination. NOAA's National Weather Service (NWS) is responsible for the overall execution of the Tsunami Program. Among its responsibilities under the Tsunami Program, NWS acquires, operates, and maintains observation systems required in support of tsunami warning, such as DART(TM). NWS also supports observations and data management through the National Data Buoy Center (NDBC). The DART(TM) II systems join NWS base stations, the Tropical Atmosphere Ocean Array, and the Coastal Marine Automated Network stations in the NOAA/NWS/NDBC Ocean Observing System of Systems (NOOSS). In the two years since being declared operational: (1) DART(TM) II systems have replaced all but three DART(TM) I systems, (2) DART(TM) network has expanded to 28 stations stretched across the Pacific and now into the North Atlantic, Caribbean Sea, and the Gulf of Mexico. (3) Three DART(TM) II systems have been provided to other countries to aid in their tsunami warning capability, (4) DART(TM) II systems provided estimated water-level information for the 2006 events in Tonga, Hawai'i, Kuril Islands, and Taiwan. In 2007, DART(TM) II systems provided observations for the Solomon Islands event and another Kuril Islands event. (5) DART(TM) II data availability for the standard mode observations have been more than 85% exceeding the target data availability goal of 80%.
