  <Summary>The Environmental Working Group (EWG) was established in June 1995 under the framework of the U.S.-Russian Joint Commission on Economic and Technological Cooperation. In January 1996, the EWG Arctic Climatology Group took on the task of compiling digital data on arctic regions to expand scientific understanding of the Arctic. This work resulted in a set of three atlases on CD-ROM for arctic oceanography, sea ice, and meteorology.

The Environmental Working Group Joint U.S.- Russian Atlas of the Arctic Ocean was developed by specialists from the Environmental Research Institute of Michigan with Russian and U.S. partners. The Atlas consists of separate volumes for winter and summer (NSIDC data set IDs G01961a and G01961b respectively). More than 1.3 million individual temperature and salinity observations collected from Russian and western drifting stations, ice breakers, and airborne expeditions were used to develop the products contained in the winter atlas. 

The primary products on the atlas are gridded mean fields for decadal periods (1950s,1960s, 1970s, 1980s) of temperature, salinity, density and dynamic height, Atlantic water layer depth, and temperature and salinity profiles and transects. The original individual observations that were used to derive these fields are not provided with the Atlas and are not available. 


Note that the 'Polar Science Center Hydrographic Climatology (PHC) ocean database (version 3.0)' is available from the Polar Science Center, Applied Physics Laboratory, University of Washington as of 18 April 2005. This is a global gridded database with a high quality description of arctic seas achieved by merging data from several sources, including data from the Environmental Working Group Joint U.S.-Russian Atlas of the Arctic Ocean.  The PHC or later versions may me more suitableyou're your research. Inquires may be sent to:
