Wave Glider NovAtel Navigation data for GNSS-A in Cascadia (2021-2023)

These NovAtel 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 Novatel files are in ASCII format and contain raw inertial navigation system navigational data from the Wave Glider in vendor-defined NMEA text logs. There are two files that contain #INSPVA and #INSSTDEV logs recorded during data collection. The #INSPVA and #INSSTDEV logs are comma-separated text data strings containing the positions, velocities, roll-pitch-heading values, and standard deviations of the inertial navigation system. The file names identify the site, date, time and Wave Glider ID. 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.
