Mainland and islands within the Salish Sea Bioregion with a database of island names, small island chain names, and larger archipelago names.Island names were derived from the British Columbia Freshwater Atlas or transcribed from Google Maps. Where no name could be find, the name field was left blank.Coastlines were defined using the Washington ShoreZone Shoreline and British Columbia Freshwater Atlas shoreline. ShoreZone was given precedence where the datasets overlapped. ShoreZone gaps like river mouths were bridged with a straight line. Shoreline line features were converted to polygons. Multipart polygons were split and inland islands were removed. The entire dataset was clipped to the Salish Sea Bioregion boundary.All processing and analysis was completed using the NAD 83 UTM Zone 10N projection and coordinate system.

1991-2020 average summer maximum temperature for the Salish Sea Bioregion. Created for the Salish Sea Atlas (wp.wwu.edu/SalishSeaAtlas).

Average summer (June-August) maximum temperature for the Salish Sea Bioregion.

1991-2020 average climate variables were statistically downscaled to 90 meter resolution using the standalone ClimateNA software based on elevations from the Salish Sea Atlas's Digital Elevation Model. The data were converted to raster format for analysis and clipped to the Salish Sea Atlas's bioregional boundary dataset. All processing and analysis was completed using the NAD 83 UTM Zone 10 N coordinate system.

For visualization purposes, raster climate datasets were reclassified into discrete ranges of values, then converted to vector polygons. Simplified attributes were calculated for each polygon.

Gridded raster versions of the data can be downloaded from the Salish Sea Atlas data portal.

This part of USGS Data Series 935 (Cochrane, 2014) presents substrate, geomorphic, and biotope data in the Offshore of Seattle, California, map area, a part of the Southern Salish Sea Habitat Map Series. Given the variable bathymetric resolution, the complex geologic history of the region, and the lack of acoustic backscatter data, automated and semi-automated classification schemes of classifying seafloor substrate and geoform were deemed to have very low accuracy. Instead, classification of these properties was performed manually following the Coastal and Marine Ecological Classification Standard (CMECS; Madden and others, 2009) using observations from underwater video footage. The best overall predictors of biotic assemblage were used to generate the CMECS biotopes. However, the nature of the biological data gathered makes it difficult to define clear biotopes. It was difficult to see or identify many organisms in the underwater video, and with an average of only 3-4 taxa identified per sampling unit, it is hard to characterize biotic assemblages. Some biological clusters of taxa were identified statistically for multiple map areas, and within each area, some of these groupings were found at consistent depths and/or with predictable substrates. The maps are not fine-grained enough to capture the physical variation seen within one-minute video units. Depth zones in the biotope map are based on Dethier (1992).

AbstractThe basin delineation was initially derived using standard watershed tools and DEM's (from NOAA). The computer generated watershed boundary was then manually edited via visual interpretation using topo maps, the DEM files and other watershed boundary maps (notably from the Sea Doc Society). The majority of the editing was in smoothing the original watershed boundary as the auto generated basin was far too detailed for the scale of the map. The smoothing process also removed the ‘raster’ artifacts. For the Salish Sea map the intent was just to show the general boundary as a smooth line that visually follows the topography. Again, the emphasis was for an easy to understand cartographic representation of the basin at a fairly coarse scale, not for exact hydrologic analysis.PurposeFor the purposes of this map & dataset, the Salish Sea was defined as including: Puget Sound, Desolation Sound (note, some BC definitions exclude Desolation Sound), Strait of Juan de Fuca (to the mouth of the Pacific Ocean), Strait of Georgia (which I defined as extending to Johnstone Strait). The Salish Sea polygon and corresponding Basin boundary files were derived for use at approximately 1:1,500,000 (e.g., Salish Sea Map, 2009, http://staff.wwu.edu/stefan/SalishSea.htm).Data creditStefan Freelan, 2009 stefan@wwu.edu 360-650-2949Institute for Spatial Information and AnalysisHuxley College of the Environment, Western Washington UniversityBellingham, WA 98225-9085http://staff.wwu.edu/stefan/SalishSea.htm
