Multibeam sonar data of the face of LeConte Glacier, southeast Alaska, 2016 - 2018

These are processed multibeam sonar data from LeConte Glacier, southeast Alaska. The data come from three cruises: 1) August 2016, 2) May 2017, and 3) September 2018. 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. References and more details: Sutherland, D.A., R.H. Jackson, C.
