High-resolution Bottom Pressure Recorder (BPR) data from DART(R) station 55015 20070414
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.

|Dataset Progress Status
|Data Update Frequency:
|| Not planned
||DART(R) stations are sited to provide in-situ tsunami detection and water-level observations
for NOAA's tsunami forecast, warning, and mitigation responsibilities.
| Use Limitations
- These data are considered raw and have not been subjected to the NOAA's quality control
or quality assurance procedures. They are released for limited public use as preliminary
data to be used only with appropriate caution. NOAA cannot assume liability for any
damages caused by any errors or omissions in the data, nor as a result of the failure
of the data to function on a particular system. NOAA makes no warranty, expressed
or implied, nor does the fact of distribution constitute such a warranty.

| Processing Steps
- Mission Start Date
- The tsunameter technology and operational responsibility for the Pacific network were
transitioned from NOAA's Pacific Marine Environmental Laboratory (PMEL) to NOAA's
National Data Buoy Center (NDBC).
| Processing Environment
||Native Dataset Environment: Raw flash card bpr data is stored as 15-sec frequency
counts of pressure and temperature. Data should be converted to engineering units
to be most useful. BPR Plotting packages have been developed to perform this conversion.
These packages are available from NGDC or PMEL.
