Sediment thickness information for the Komandorsky Basin in the Bering Sea comes from isopach contours published in Figure 3 of Baranov and others (1991), based on single-channel and multichannel seismic reflection data collected in the Komandorsky Basin in the 1970s and 1980s. The Figure 3 map of Baranov and others (1991) was scanned and georeferenced (BaranovEtAl-1991-Figure3-GeoreferencedScan.tif), and the isopachs and other geological features were digitized and output as vector shapefiles. A raster grid of sediment thickness in GeoTIFF format (KomandorskyBasin-SedimentThicknessGrid.tif) was created from the digitized isopachs, within a masking polygon in shapefile format (BaranovEtAl-1991-Figure3-Edge_of_Coverage.shp) based on the extent of the isopachs. In initial testing, the gridding algorithm did not extrapolate well to the outer edge of the coverage, generating grid values that yield contours not observed in the published figure. Thus, a CSV file of manually determined minimum and maximum sediment thickness constraint values (KomandorskyBasin-SedimentThickness-ManualConstraints.csv) was generated to guide the gridding algorithm in areas near the edge of the grid coverage to avoid grid values that would generate false contours. Each data file, along with a corresponding CSDGM FGDC-compliant metadata file, is provided in its own zip archive file.
