The following is a list of Environmental Sensitivity Index (ESI) atlases by region (Atlantic Coast, Gulf of America, Pacific, Great Lakes, and U.S. Territories), their publication dates, and atlas numbers. To interpret this table:

• An asterisk (*) in the Atlas Number column denotes that the ESI atlas is not available in digital (GIS) format and is published as a hardcopy product only.
• The asterisk in the Publication Date column for the Texas Lower Coast ESI denotes that the atlas was not published by NOAA, therefore did not follow ESI Guidelines.
• Some regions have been published in GIS format more than once. These are indicated with earlier versions noted in parentheses. 

The maps and data making up these atlases are downloadable for free from the ESI Downloads page. As new atlases are published, this list will be updated.
 

Atlas Number Assignment

The atlas number assigned to each atlas is generally dependent upon the atlas number of the initial publication, if applicable. If the current atlas is a second edition, a ‘200’ would typically be added to the number of the initial publication. For example, using the table above, the Southern California atlas was initially published in 1995 with an atlas number of 9. The second edition of this atlas (covering the same geographic area) published in 2010 was assigned the atlas number of 209. This pattern is not followed if adding 200 would create a conflict with existing atlas numbers or if a specific number is requested by NOAA. In general, atlas numbers are selected to preserve space for future editions within the existing numbering structure.
