These are processed multibeam sonar data from LeConte Glacier, southeast Alaska. The data come from two cruises: 1) August 2016 and 2) May 2017. Note these data are of the ice face itself, excluding any seafloor data (which can be found here - LeConte Bay Seafloor Elevation Data 1999 - 2018. https://doi.org/10.18739/A21J97859). They are in World Geodetic System 1984 (WGS84) and Universal Transvers Mercator (UTM) zone 8 horizontal (meters in easting/northing). There are several different passes of the ice face included for each year, which you can identify by the assigned time stamp. Reference and more details: Sutherland, D.A., R.H. Jackson, C.
