Cowthkg.tif is a 1000-m resolution grid of sediment thickness derived from contours (cowiso.shp, also in this data set) from 1:1,000,000-scale Map Showing Sediment Isopachs in the Deep-sea Basins of the Pacific Continental Margin, Strait of Juan de Fuca to Point Loma, California (Gardner and others, 1992, 1993a, 1993b). The maximum sediment thickness in this region is 2342 m with a mean value of 359 m.
These data are intended for science researchers, students, policy
makers, and the general public. The data can be
used with geographic information systems (GIS) software
to display geologic and oceanographic information.

Contour data (cowiso.shp, 100-m interval from 0 to 2300 m) from which
this grid was generated have a displacement of as much as 10km.
The contours of sediment thickness from which this grid was derived may vary as
much as 10 percent throughout the range of seismic-reflection travel times

A 1000-m grid was constructed from the following inputs to ArcGIS TopoToRaster tool: (1) digital contours from construction of 1992-1993 sediment thickness maps (cowiso.shp, also in this data set), and (2) points with value 0 enclosed by outlines of "outcrop."

TopoToRaster interpolation produced negative thicknesses, which were recalculated to 0. Final grid was clipped to extent of source contours.
