Description: Marspec Concavity: Using the Surface tools within the Spatial Analyst toolbox in ArcGIS 9.3.1, six geophysical variables were derived from bathymetry to characterize different facets of aspect, slope, and terrain curvature of the seafloor. terrain curvature were calculated in order to characterize how ocean bottom currents might interact with the seafloor. Concavity is the second derivative of the bathymetry layer (or the slope of the slope) and represents whether a raster cell is on a hill (negative values) or in a valley (positive values).
