Title:
Gridded bathymetry data (GMT netCDF format) for the Discovery Transform Fault and possible nano-plate
Abstract:
This multibeam gridded bathymetry data set was collected using an EM300 swath sonar system during R/V Thomas Thompson cruise TN214. The primary goal of the cruise was to deploy 40 ocean bottom seismometers (OBS) and 7 seafloor geodesy tripods at the Quebrada/Discovery/Gofar (QDG) transform fault system on the equatorial East Pacific Rise. There were three target survey areas for high-resolution seafloor mapping: the Discovery and Quebrada transform faults, and a potentially rotating nano-plate just north of the Discovery transform fault. The surveys were typically carried out at a survey speed of 5 knots, with a fixed swath width of 4 km (135 beams/ping). The bathymetry was processed using the CARIS Hips&Sips software. The data file is in GMT-compatible netCDF grid format, gridded at a resolution of 75m with no interpolation to fill data gaps, WGS-84. The gridded TN214 bathymetry data is used in the Wolfson-Schwehr et al., 2014 paper. This project was funded by NSF Award 0242117, with Principal Investigators Jeffery McGuire, John Collins, and Robert Detrick.
