Arctic Ocean Reference

This map includes marine water body names, undersea feature names, and derived depth values for use with the Arctic Ocean Base map.

Map Service Name: Arctic_Ocean_Reference

Note:

The Arctic Ocean Reference layer is not included with Collection 1.

Description

The Arctic Ocean Reference layer is designed to be used as the reference layer for the Arctic Ocean Base map. The reference layer includes marine water body names, undersea feature names, and derived depth values in meters. Features over land include administrative boundaries and labels and cities.

The reference layer was compiled from a variety of best available sources from several data providers, including General Bathymetric Chart of the Oceans GEBCO_08 Grid, IHO-IOC GEBCO Gazetteer of Undersea Feature Names August 2010 version (www.gebco.net), the National Oceanic and Atmospheric Administration (NOAA), and National Geographic, Garmin, Geonames.org, and Esri, and various other contributors. For details on the Community users who contributed bathymetric data for this map through the Community Maps Program, see Contributors in the Arctic Ocean Base description.

The Arctic Ocean Reference map currently provides coverage down to a scale of ~1:881,000. The Arctic Ocean Reference map can and will be extended with higher-resolution bathymetric data. You can contribute your bathymetric data to this map and have it served by Esri for the benefit of the GIS community. For more information on how to contribute data, contact [e-mail].

Note:

Data from the GEBCO_08 Grid shall not be used for navigation or for any other purpose relating to safety at sea. The GEBCO_08 Grid is largely based on a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. In some areas, data from existing grids are included. The GEBCO_08 Grid does not contain detailed information in shallower water areas, and information concerning the generation of the grid can be found on GEBCO website at www.gebco.net/data_and_products/gridded_bathymetry_data/. The GEBCO_08 Grid is accompanied by a Source Identifier (SID) Grid, which indicates which cells in the GEBCO_08 Grid are based on soundings or existing grids and which have been interpolated. The latest version of both grids and accompanying documentation is available to download, on behalf of GEBCO, from the British Oceanographic Data Centre (BODC) website at www.bodc.ac.uk/data/hosted_data_systems/gebco_gridded_bathymetry_data/. The names of the IHO (International Hydrographic Organization), IOC (Intergovernmental Oceanographic Commission), GEBCO (General Bathymetric Chart of the Oceans), NERC (Natural Environment Research Council) or BODC (British Oceanographic Data Centre) may not be used in any way to imply, directly or otherwise, endorsement or support of either the Licensee or their mapping system.
