This study focuses on a 67 attribute lake cover classification scheme covering the Bering Land Bridge area of the Seward Peninsula, Alaska. The GIS dataset consists of 5170 lakes (which were extracted from a 5m resolution ifSAR/orthophoto image) and provides information on lake morphometry, hydrologic connectivity, surface area dynamics, surrounding terrestrial ecotypes, bedfast percentage, and other important conditions. The Seward Peninsula lake habitat study classification system provides lake specific information for a coastal peninsula area that will guide research and aid in the management of the natural environment.
