The vector data file is included in "CMECS_AdmiraltyInlet.zip," which is accessible from http://pubs.usgs.gov/ds/935/AdmiraltyInlet/data_catalog_AdmiraltyInlet.html. 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). The CMECS Geoform map (Sheet 2) and the CMECS Substrate map (Sheet 3) display their CMECS variable counterparts found in the CMECS polygon shapefile. The best overall predictors of biotic assemblage were used to generate the CMECS biotope map (Sheet 4) which displays the biotope variable in the CMECS polygon shapefile. 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 video; with an average of only 3-4 taxa 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. The biological data suggest that to some degree these combinations of physical parameters correspond to ‘biotopes’, i.e. that there is some level of predictability about the associations of plants and animals that will be found with different combinations of geological and oceanographic parameters. Depth zones in the biotope map are based on Dethier (1992). References Cited: Dethier, M.N. 1992. Classifying marine and estuarine natural communities: an alternative to the Cowardin system.

Review drafts of the map were reviewed internally by at least two other geologists for consistency with basic geologic principles and general conformity to USGS mapping standards. 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. The smallest area represented is approximately 200 square meters. 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 from bathymetric lidar and sonar surveys (see sheet 1, OFR 2015-1073). Sea floor video and sediment sample informtion 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. There is no elevation data in the database.

Process_Step: Process_Description: Map unit Geoform polygons were digitized over underlying 2-meter base layers developed from multibeam bathymetry 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 bathmetric surveys and USGS seismic reflection profiles in combination with knowledge of common glacial and estuarine processes and interpretations from the regional geologic literature References Cited: Madden, C.J., K. Goodin, R.J. Allee, G. Cicchetti, C. Moses, M. Finkbeiner, D. Bamford. 2009. Coastal and marine ecological classification standard (Version 3). NOAA and NatureServe. 126 pp. http://www.csc.noaa.gov/benthic/cmecs/ Process_Date: 2012 Process_Step: Process_Description: The CMECS Substrate Component values are described in Madden and others (2009). Areas near USGS seafloor video transects, within the primary study region (colored areas in figure 2-1) 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 form 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. Only data for offshore map units are released digitally in this publication.

Depth zones in the biotope map are based on Dethier (1992). The biotope polygons were derived by merging 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.
