This map includes bathymetry overlaid on land-cover and shaded relief for the Arctic polar region.
Map Service Name: Arctic_Ocean_Base
Note:
The Arctic Ocean Base map is not included with Collection 1.
Description
The Arctic Ocean Base map features marine bathymetry. This layer is designed to be used as a basemap by marine GIS professionals and as a reference map by anyone interested in ocean data. Land features include inland waters and roads overlaid on land-cover and shaded relief imagery. This web map allows you to view the Arctic Ocean Base with the Arctic Ocean Reference layer drawn on top.
The map was compiled from a variety of best available sources from several data providers, including General Bathymetric Chart of the Oceans GEBCO_08 Grid version 20100927, the International Bathymetric Chart of the Arctic Ocean, and the National Oceanic and Atmospheric Administration (NOAA) for the oceans; and Garmin, and Esri for topographic content.
The Arctic Ocean Base currently provides coverage down to a scale of ~1:881,000. The Arctic Ocean Base 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 about how to contribute data, contact Oceanbasemapteam@esri.com.
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.Contributors
The following table names the current Community Maps Program contributors to the Arctic Ocean Basemap hosted by Esri and provides information on their specific content. The basemap was compiled to uniform cartography using a variety of best available sources from these data providers.
