Beach topography and near-shore bathymetry of Lake Superior at Minnesota Point and the Duluth Entry, Duluth, MN, 2020 (ver. 2.0, September 2024)

This dataset represents elevation data of the beach topography and near-shore bathymetry of Lake Superior at two locations along Minnesota Point, Duluth, Minnesota. LiDAR data were collected using a Velodyne VLP-16 unit representing the beach topography, and multibeam sonar data were collected using a Norbit integrated Wide Band Multibeam System compact (iWBMSc) sonar for bathymetry. The dataset includes DEMs of the terrestrial beach areas and topobathy (combined terrestrial and bathymetry), LAS and XYZ files of LiDAR and multibeam data, and 2-ft contours of the surveyed areas. Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District, to define beach topography and near-shore bathymetry before and after placing dredge spoils to mitigate beach erosion.
