Abstract:
These data files were collected as part of GNSS-A operations on the Cascadia Subduction Zone, and can provide estimates of crustal deformation rates along the plate boundary. The data were collected on missions starting in 2021 by a remotely-operated Wave Glider system. The Wave Glider collects GNSS data while ranging to an array of seafloor transponders. All of the GNSS-A sites are located on the accretionary prism. The acoustics files are ASCII csv files that contain the acoustic ranges and QC metrics for each acoustic reply received by the Wave Glider. There is one acoustics file for each transponder in an array for a given survey, and the file names contain the site, year, Wave Glider, and unique ID of the transponder. The files were generated with NSF funding as part of the project called Constraints on Interseismic Locking near the Trench on the Oregon Segment of the Cascadia Subduction Zone Using Seafloor Geodesy (GNSS-A), funded with NSF awards OCE21-27140 and OCE21-26396.
