rs, 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

combining codes or overcodes to aggregate water bodies. The recently
delimited Southern Ocean is not included.
