Sea floor ruggedness analysis for the Stellwagen Bank National Marine Sanctuary region (rugged)

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.
