DIAM 65-18:?Geopolitical Data Elements and Related Features,
Data Standard No. 4, Defense Intelligence Agency Manual 65-18, December
1994, published by the Defense Intelligence Agency
The US Government has not yet adopted a standard for hydrographic codes
similar to the Federal Information Processing Standards (FIPS) 10-4 country
codes. The names and limits of the following oceans and seas are not always
directly comparable because of differences in the customers, needs, and
requirements of the individual organizations. Even the number of principal
water bodies varies from organization to organization. Factbook
users, for example, find the Atlantic Ocean and Pacific Ocean entries
useful, but none of the following standards include those oceans in their
entirety. Nor is there any provision for combining codes or overcodes
to aggregate water bodies. The recently delimited Southern Ocean is not
included.
