High-resolution Bottom Pressure Recorder (BPR) raw data from DART(R) station 52406_2008_2
20080330 to 20090911
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.

DART II Description and Disclosure
- Description of Source: Source Contribution: Processing steps for BPR data after recovered. Source Type: paper
- Temporal extent used:
1998-07-03 to present
|| Lineage statement not available.
| Processing Steps
- Binary data file is received for long-term archive.
- 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 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 NCEI or PMEL.
