Is there a file that lists the bodies of water returned by the ocean service? I was surprised to learn that it includes the Great Lakes, so I'm curious which other "inland seas" have been identified.
By the way this is more than idle curiosity; since countrySubdivision always returns a US or CA location for the entire Greats Lakes, my system doesn't automatically check the ocean service for a value like Lake Michigan. Rather than double-dip for every location, I'd like to add an override for the areas that have lakes in the ocean database. It appears to be a short list.
