LeConte Bay Seafloor Elevation Data

<p>Multibeam data of LeConte Bay seafloor from the inner fjord.</p> <p>These are processed multibeam sonar data from LeConte Bay, southeast Alaska. The data come from five cruises grouped into five files:<br> 1) Aug 1999 and Sep 2000 (20-m resolution) - 1 file;<br> 2) August 2016 (20-m and 4-m resolution) - 2 files;<br> 3) May 2017 (2-m resolution) - 1 file;<br> 4) Sep 2018 (2-m resolution) - 1 file.</p> <p>The datasets collected in 2016-2018 originally included ice-face data, as reported in Sutherland et al., 2019 (DOI 10.1126/science.aax3528). The data presented here include only the seafloor data, exclusive of the ice face. They are referenced to WGS84, UTM zone 8 (meters easting/northing), and mean sea level.</p> <p>Reference and more details: Eidam, E.F., Sutherland, D.A., Duncan, D., Kienholz, C., Amundson, J.M., Motyka, R.J.
