Salish Sea Bathymetry Basemap
Bathymetric Base Map for the Salish Sea Bioregion. Created for the Salish Sea Atlas ( https://wp.wwu.edu/salishseaatlas/).
Bathymetry for the Salish Sea. 3-arc second (approximately 90 meter) spatial resolution. Vertical datum: approximately Mean Sea Level.
Separate datasets for British Columbia and Washington data were downloaded from NOAA, converted from NetCDF to raster, and then combined as a Mosaic dataset using "blend" where they overlapped. The combined dataset was re-projected to UTM using Cubic Convolution resampling. The bathymetry dataset was snapped to align with the grid cells of the Salish Sea Atlas's Digital Elevation Model and clipped to the Salish Sea Atlas's Marine Waterbodies dataset. Low-lying coastal areas with missing data due to small mismatches in the coverage of bathymetry and elevation data in Canada were corrected by recalculating the elevation as 0 meters asl.

- Supplemental Information
-
Canadian data came from NOAA's British Columbia Bathymetric Digital Elevation Data.
US Data came from NOAA's Coastal Relief Model.
Note that this dataset was created using multiple datasets in different vertical datums. NOAA says that "the differences between these datums are less than the vertical accuracy of the CRM, so you can assign Mean Sea Level to this DEM if you like, just recognize that the elevation values may not be as accurate as you might like or need. Assume a vertical accuracy no better than 1 meter for any elevation values."
