Randolph University of Rhode Island, Graduate School of Oceanography (GSO) author Donohue, Kathleen A. author Wei, Meng author University of Rhode Island, Graduate School of Oceanography (GSO) contributor tableDigital This data set contains vertical acoustic travel time, bottom pressure and temperature, as well as near-bottom current and temperature taken by four current and pressure recording inverted echo sounders (CPIES) near the Cascadia subduction zone offshore of Oregon from 2017-04-27 to 2017-11-11. Travel time and pressure measurements from two additional PIES (lacking the integrated current meter) are included. Near-bottom velocities were also measured by a current meter on a separate mooring between August and November 2017. The CPIES data are the highest quality versions with the least amount of processing. The collection and processing of the data are described in the report provided. Data are in NetCDF. These data were collected to provide measurements of the ocean currents in a region where slow-slip tectonic events can occur.
