Sea floor ruggedness analysis for the Stellwagen Bank National Marine Sanctuary region
Entry ID: CZM_moris_rugged_raster_1.0


Summary
Abstract: The Terrain Ruggedness Index (TRI) calculates the average difference in elevation between a small area (a center pixel of 13 x 13 m) and its surrounding area (neighboring pixels). The TRI was applied to the digital bathymetric grids of the seafloor of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts to create an analysis of sea floor ruggedness.

Purpose: The Terrain Ruggedness Index provides an interpretation of the seabed features in the highly variable geomorphology of the Stellwagen Bank National Marine Sanctuary region. The seabed geometry is variable due to its glacial origin and is important to the region's wide range of habitats and high biodiversity. Note: These data were reprojected from their native projection into North American Datum ... View entire text
