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.
