Cascadia_Wilcock Pressure, Temperature
Continuous seafloor APG pressure and temperature data from trench-perpendicular benchmarks on the Cascadia margin, offshore central Oregon
This data set presents Absolute Pressure Gauge (APG) pressure and temperature time series data from a set of seafloor benchmarks running trench-perpendicular on the Cascadia margin, offshore central Oregon, beginning in 2015. The pressure gauge sensors were made by Paroscientific and the platforms were designed and deployed by the University of Washington School of Oceanography and Applied Physics Lab (APL). The sensors were attached to free-fall deployed concrete benchmarks designed to also serve as a platform for the Scripps Institution of Oceanography’s Absolute Self-Calibrated Pressure Recorder (ASCPR), to obtain campaign-style drift-free reference pressures (not included in this data set). APGs collect absolute pressure (PSIA, dbar) and temperature (degrees C) data at a period of 100 seconds, and were deployed with battery packs and data storage sufficient for 10 years of data collection. The data were transferred in-situ via wireless communication with an ROV. Each data file is in ASCII comma-separated format and contains continuous time series data from a single sensor. No processing has been done beyond the conversion from counts to physical units - see the calibration sheets in the associated data set. Some sensors failed in 2016 and were redeployed the following year, resulting in separate data files. Instrument deployment and recovery operations were performed during cruises TN332, SKQ201607S, SKQ201705S, RR1716. This data set was generated as part of the project called Constraints on Interseismic Deformation Offshore Oregon from Calibrated Continuous Pressure Records. Funding was provided through NSF award OCE15-58477.
