CHIRP subsurface seismic data These data are raw .sgy files of CHIRP subsurface data collected from LeConte Bay, Alaska (AK) in September 2017, as part of a study aimed at investigating sedimentation in front of a retreating tidewater glacier. We acquired more than 45 kilometers (km) of sub-bottom sonar profiles across- and along-fjord. A .nc (netcdf) file of aggregated xy location data and other metadata is also included for ease in viewing data extents. Reference and more details: Eidam, E.F., D.A. Sutherland, D. Duncan, C.
