Name: Aquatic ecological units

Display Field: Depth

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: We identified and mapped 77 aquatic ecological units (AEUs) that depict unique 14 combinations of depth, thermal regime, hydraulic, and landscape classifiers. Those 77 AEU types were distributed across 1,997 polygons (patches) ranging from 1 km2 to > 48,000 km2 in area and were most diverse in the nearshore (35 types), followed by the coastal margin (26), and then the offshore (16). Our classification and mapping of ecological units captures gradients that characterize types of aquatic systems in the Great Lakes and provides a geospatial accounting framework for resource inventory, status and trend assessment, research for ecosystem questions, and management and policy-making.
