Bathymetric model of Lake Joyce, McMurdo Dry Valleys, Antarctica

An updated bathymetric model was developed for Lake Joyce, located in the McMurdo Dry Valleys of Antarctica. The model integrates a published history of lake level rise from 1947 to 2014, historical lake depth soundings, digitized shoreline positions from both historical and modern aerial imagery, and subsurface bedrock topography from Taylor Glacier. The resulting dataset includes model-derived estimates of depth, map-projected area, lakebed surface area (factoring in slope), and water volume at 1-meter depth intervals.
