MontereyCanyon_CCE Pressure, Temperature
Range, orientation, temperature and pressure data recorded with AMT beacons in Monterey Canyon, offshore California
An array of three Sonardyne Acoustic Monitoring Transponders (AMTs) was placed in Monterey Canyon to monitor small scale seafloor movements (creep) as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Each instrument was in place for deployments lasting up to six months beginning in October 2015 and October 2016. One AMT was placed at 300 meters water depth in the canyon axis and the other two on stable benches on the canyon sides. The central AMT, deployed in the axis on a large (800 kg, >2 m tall) frame, also had a BED mounted to the side. Each AMT recorded the acoustic range to the other instruments as well as pitch, roll, temperature, and depth every 45 minutes. The data files are in ASCII comma-separated format. File names begin with MBCCE, then mooring name, followed by the date range of the collected data (yyyymmdd to yyyymmdd). For more specific information about each data file, download the excel file "CCE Files and Stations" and review the "Science Report" under Documents. Funding for the project was provided by The David and Lucile Packard Foundation, Natural Environment Research Council (NE/K011480/1), U.S. Geological Survey, Ocean University of China, and Qingdao National Laboratory for Marine Science and Technology.
