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; Federal Geographic Data Committee, 2012) 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). Purpose: To expand geologic mapping to the seafloor within Washington's State Waters, to update coastal habitat mapping, and to contribute to a uniform regional habitat database. Additionally, to provide a habitat map for the public and ecoscience community to aid in land-use and land-management decisions both onshore and offshore.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Polygons were hand delineated; the accuracy of substrate and biota observations cannot be quantified. Polygons were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the lead author and by the GIS technician who created the digital database. Logical_Consistency_Report: No checks for consistency were performed on this data. Completeness_Report: Data are complete, no offshore features that could be accurately identified and represented at the compilation scale of 1:30,000 were eliminated or generalized. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Polygons were primarily mapped by interpretation of 2-meter-resolution hillshaded bathymetry data interpreted from bathymetric lidar and sonar surveys (see BathyTopo data available in this data release), from visual observations of underwater sea floor video (also available in this data release), and from sediment samples (Reid and others, 2006). Sea floor video and sediment sample information positions are highly variable, on the order of 10 meters. Horizontal position given is ship position. Towed camera can be on the order of 10 meters distance from the ship during deployment. Map Unit contact locations were interpreted typically at a scale of 1:2,000 using the above base data. Bathymetric sonar and LiDAR data have a horizontal accuracy greater than the resolution of the base data. Map unit contacts were digitized by heads-up screen digitization of line data on 2-meter-resolution DEMs described above. Horizontal accuracy is estimated to be between 2 and 5 meters depending on how clearly contacts can be resolved. Most digitized positions on the map are estimated to have better than 5 m horizontal accuracy. Lineage: Process_Step: Process_Description: Map unit Geoform polygons were digitized over underlying 2-meter base layers developed from multibeam bathymetry data, available elsewhere in this data release (BathyTopo_OffshoreTacoma data). The specificity of our CMECS geoform interpretations reflects the resolution of the underlying NOS bathymetry. Where there was sufficient resolution to attribute a particular genetic process to a geoform, we ascribed an appropriately specific geoform type. Where bathymetric resolution was low and the genetic interpretation equivocal, our geoform classifications were more generic. Seafloor geoforms were classified based on their physical attributes as observed in the NOS bathymetric surveys and USGS seismic reflection profiles from field activities G395PS and G297PS (Triezenberg and others, 2016) in combination with knowledge of common glacial and estuarine processes and interpretations from the regional geologic literature (Ballantyne, 2002; Booth, 1994; Burns, 1985). Process_Date: 2012 Process_Step: Process_Description: Areas near USGS seafloor video transects were classified with more specificity, down to Substrate Group or Substrate Subgroup, depending on proximity to ground-truthed transects and the local heterogeneity of the seafloor. Our classification of substrates in areas outside the primary study region was based primarily upon geomorphological interpretations drawn from historical NOS surveys and historical NOS seabed descriptions. Consequently, these interpretations are less specific; substrate classifications in these areas are typically limited to the Substrate Class or Substrate Subclass. The CMECS Substrate Component values are described in Federal Geographic Data Committee (2012). Process_Date: 2012 Process_Step: Process_Description: Depth zones classes in the biotope map are based on Dethier (1992). The biotope polygons were derived by merging (using the ArcGIS union tool) depth zone polygons with the CMECS geoform-substrate polygons and creating an integer code to represent the substrate class and depth zone of each polygon. A depthzone attribute was created that has Dethier (1992) attribute values.
