Acoustic Travel Time data for GNSS-A in Cascadia (bcsonardyne ASCII files)
These data 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 2016 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 bcsonardyne files are in ASCII format and contain raw two-way acoustic travel time between the Wave Glider transducer and the seafloor transponders.The file names identify the site, date, time and Wave Glider ID. The data files were generated with NSF funding as part of the projects called Constraining Slip Distribution of the Cascadia Subduction Zone Offshore Central Oregon with Seafloor Geodesy; and, Assessing the State of Locking on the Frontal Thrust of the Cascadia Subduction Zone With Seafloor Geodesy.
