Detailed Methodology for the National Estuary Assessment (Step 2)

from the National Fish Habitat Partnership's 2015 Through a Fish's Eye Report


Integrating Data into the Spatial Framework This assessment investigated the effects of anthropogenic stressors on 220 estuaries in the conterminous U.S. The nested spatial framework, identical to the one used in 2010, was used to assemble and analyze spatial habitat data. The framework defined four units (see Figure 7) to analyze human effects on estuaries: Estuaries: Range from relatively small river mouths (e.g. Carmel River Mouth) to large bays (e.g. San Antonio Bay), and also include some very large and complex estuary systems (e.g. Chesapeake Bay) as well as deep inland seas (e.g. Puget Sound). Estuaries are delineated as distinct units except for very large systems with many tidal tributaries, which are divided based on natural [...]
