California_Sheephead_Entire_Adult_Distribution

                            This shapefile contains the most common distribution for adults.  The process of creating this shapefile included creating contour lines, in 5 meter intervals, from bathymetry lines.  Depth ranges were taken from four references (see below).  After the depth range between which this species is most common was determined, they were rounded to the closest 5 meter interval.  The deepest and shallowest shapefile lines were connected by a line at the northern end and southern end (determined by their geographical range from north to south). This shapefile was then converted to polygon.   The goal of this shapefile was to provide a range in which this species could occur, given that their habitat is present.

Shapefile Description

This shapefile contains the entire distribution for adults.  The process of creating this shapefile included creating contour lines, in 5 meter intervals, from bathymetry lines.  Depth ranges were taken from four references (see below).  After the broadest depth range was determined for this species, they were rounded to the nearest 5 meter interval.  The deepest and shallowest shapefile lines were connected by a line at the northern end and southern end (determined by their geographical extent from north to south). This shapefile was then converted to polygon.   The goal of this shapefile was to provide a range in which this species could occur, given that their habitat is present.
