Five-minute grid of marine bird density off central California - Davidson Current seasons, 1980-2001 (CDAS data set Da0_dens.shp)

Description

Da0_dens is a polygon shapefile representing 5 minute x 5 minute latitude x longitude cells that contain the overall, combined densities (birds/sq km), of 76 species of marine birds in the CDAS central CA data set, for the Davidson Current Season (Nov15-Mar14). The number of marine birds seen in a cell was divided by the area sampled in the cell to estimate density. If a cell was censused more than once, densities were averaged. Cells that were surveyed but in which no birds were observed have densities of zero.
