Online_Linkage: https://cmgds.marine.usgs.gov/data/walrus/anadbath.zip Description: Abstract: Bathymetric contours were generated from soundings collected during surveys and cruises by the Hydrographic Office, National Ocean Survey, and Coast and Geodetic Survey. The region covered by the map is the Bering Sea Shelf from Bristol Bay, Alaska to the Gulf of Anadyr, Russia. Bathymetry is in meters at 10 m intervals, with 5 m supplemental contours. The digitized portion includes the Anadyr Gulf and Bering Strait in Russian waters (west of the Exclusive Economic Zone), to supplement digitized National Ocean Service maps of U.S. waters (Coastal Shelf Bathymetry of the Bering, Chukchi, and Beaufort Seas). The original paper map was produced by the Geological Society of America and published in 1974. The map is no longer in print from the Geological Society of America (3300 Penrose Place, Boulder, CO 80301) but may be available at natural resource agency libraries that include literature on Alaska and/or Russia. In 1997, the USGS digitized the bathymetric contours for research purposes. Purpose: The map was produced by The Geological Society of America during a period of mineral and seismic exploration in the Bering Sea. The map was digitized by the USGS for purposes of marine animal research. Supplemental_Information: The USGS Alaska Science Center created these digital bathymetry coverages to support marine animal research in the Bering and Chukchi Seas. The completed coverages are being stored on the Coastal and Marine Geoscience Data System (CMGDS) for archival purposes only. The coverage "GSA Gulf of Andyr Bathymetry" is titled ANADBATH_3GEO (anad=Anadyr Gulf, bath=bathymetry, 3=polygon topology, geo=geographic projection) Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1974 Currentness_Reference: map publication date Status: Progress: Complete Maintenance_and_Update_Frequency: None Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -180 East_Bounding_Coordinate: -168 North_Bounding_Coordinate: 66 South_Bounding_Coordinate: 60 Keywords: Theme: Theme_Keyword_Thesaurus: USGS Metadata Identifier Theme_Keyword: USGS:06dc6880-12a8-4b61-a8b1-2d68160abe9d Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme_Keyword: oceans Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: contours Theme: Theme_Keyword_Thesaurus: Data Categories for Marine Planning Theme_Keyword: distributions Theme_Keyword: bathymetry and elevation Theme: Theme_Keyword_Thesaurus: USGS Thesaurus Theme_Keyword: bathymetry Theme_Keyword: contouring Theme_Keyword: computational methods Place: Place_Keyword_Thesaurus: None Place_Keyword: western Alaska Place_Keyword: eastern Russia Place_Keyword: Anadyr Gulf Place_Keyword: Bering Sea shelf Access_Constraints: None Use_Constraints: Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Attribute accuracy was tested by manually comparing hard copy plots to the source maps. Accuracy of the source maps is related to the contouring algorithm used to derive the contours, accuracy and density of soundings used to generate contours, and changes in bathymetry since the data were collected. Logical_Consistency_Report: All polygon features are checked for topology using Arc/INFO software. Each polygon begins and ends with a node feature. All nodes are checked for errors so that there are no dangling features. There are no duplicate lines or polygons. All nodes well snap together and close polygons based on a specified tolerance. If the node is not within tolerance it is adjusted manually. The tests for logical consistency are performed in Arc/INFO. Completeness_Report: Contours were digitized from the Bathymetric Map of the Bering Shelf published by The Geological Society of America. Contours were digitized at 10 m intervals to 200 m. Intermediate 5 m contours were not included in the GIS product because many were dangling arcs that could not be used to build polygons. Contours beyond 200 m are available on the source map, but were not included in the digitized product. Only the part of the map in Russian waters (west of the Exclusive Economic Zone) was digitized to provide a compliment for the Coastal Shelf Bathymetry map (see cross-references). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positional accuracy was tested using Arc/INFO's RMS errors generated when the digitized map is converted from table inches to real world coordinates. RMS errors were low.

An additional strip was digitized on the U.S. side of the Exclusive Economic Zone, providing overlap to the Coastal Shelf Bathymetry map to allow for edge-matching by product users. Contours were digitized at 10 m intervals except where contours were missing from the source map. Work was performed in part by Resource Data, Inc., Anchorage, Alaska.
