Gridded Data from Multibeam Bathymetric Surveys of Eklutna, Kenai, and Skilak Lakes, Alaska
This dataset contains bathymetric depth values for three lakes in southcentral Alaska: Eklutna Lake near the city of Anchorage, Kenai Lake near the city of Cooper Landing, and Skilak Lake near the city of Soldotna. Values are in negative meters and measured relative to the North American Vertical Datum of 1988. The data release consists of a raster grids (Eklutna = 4 m; Kenai = 9 m, Skilak = 7 m), derived from processed and cleaned multibeam data. Depths were corrected using conductivity, temperature, and depth profiles collected during the surveys, and the data were cleaned of spurious returns.
