Count Component Title Abstract
1 High-resolution Bottom Pressure Recorder (BPR) data from DART(R) station 55015 20070414 to 20090306 The Deep-ocean Assessment and Reporting of Tsunamis (DART(R)) is an ongoing, multi-agency cooperative effort to maintain and improve the capability for the early detection and real-time reporting of tsunamis in the open ocean. The DART(R) network is an essential component in the provision of timely warnings to U.S. coastal communities. DART(R) data support the NOAA Tsunami Program observation requirements for Tsunami Offshore Real-Time and Post-event observations, as well as Global Water Level Observations. Each DART(R) system consists of an anchored seafloor Bottom Pressure Recorder (BPR) acoustically coupled to a moored surface buoy. Iridium transceivers and the acoustic modems provide real-time communication between each DART(R) system and the Tsunami Warning Centers (TWC) in Ewa Beach, Hawai`i and Palmer, Alaska. Additionally they provide limited communications from the TWC to the BPR. DART(R) BPR packages are deployable for 48 months at depths up to 6000 meters and are typically on a 24-month service schedule. The BPR is recovered by sending a signal to trigger an acoustic release causing it to mechanically separate from the anchor. Flotation brings the unit to the surface, leaving the anchor on the seafloor. Meinig, et. al. (2005) provides a description of DART(R) and its performance characteristics.

        1 Depth The ship-measured depth (meters) of the ocean at which the buoy was moored. The ship-measured depth is not as accurate as the BPR-measured pressure. To obtain the most precise depth, convert the bottom pressure to depth. If value is 99999, depth is unknown.
        1 Threshold The pre-programmed threshold in the bottom pressure recorder. If the water level exceeds this threshold, the tsunami detection algorithm sends the bpr into event recording mode.
