Multibeam sonar data of icebergs from LeConte Glacier, southeast Alaska, June 2022 - July 2023

These data include processed multibeam sonar and drone-derived three-dimensional point clouds of icebergs surveyed between 2022 and 2023 in Xeitl Geeyí’ (LeConte Bay), Southeast Alaska. Thirteen grounded icebergs were mapped using Norbit iWBMS and Winghead i77h/i80s sonars, and one recently capsized floating iceberg was mapped using a DJI Air 2S drone. The datasets were collected to quantify submarine iceberg morphology and surface roughness as part of a broader effort to improve understanding of ice–ocean interactions at near-vertical ice-ocean boundaries. The methods and analyses are described in Cohen et al. (submitted in 2025), "Characterizing submarine ice roughness at icebergs from a temperate tidewater glacier", under review in the Journal of Glaciology. All data are georeferenced to World Geodetic System 1984 (WGS 84) and Universal Transverse Mercator Zone 8 N (meters in easting/northing).
