BPR Data for WC52 19930801 to 19940801

During 1982-1985, PMEL engaged in the development of a reliable deep-ocean Bottom Pressure Recorder (BPR) to collect high-quality deep-water data during a tsunami. In 1986, NOAA initiated a long-term field program in the northeast Pacific and the program was expanded in 1987 to include shallow-water BPR sites maintained and operated by the United States Army Corps of Engineers along the United States west coast and Hawaii. The Pacific Tsunami Observation Program (PacTOP) included five permanent deep-ocean observational sites in the northeast Pacific Ocean to monitor the seismically active Alaska-Aleutian Seismic Zone because of the potential threat to United States coastal regions. During the mid-90's, the individual BPR package is now part of a real-time tsunami detection package, the Deep-ocean Assessment and Reporting of Tsunamis (DART). The National Geophysical Data Center (NGDC) serves as the archive center for this data and provides the historical data to users.
