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. DART(R) stations are sited to provide in-situ tsunami detection and water-level
observations for NOAA's tsunami forecast, warning, and mitigation responsibilities. M.C. Eble F.I. Gonzalez D.M. Mattens H.B. Milburn DOC/NOAA/OAR/PMEL > Pacific Marine Environmental Laboratory, OAR,
