have you tried using the ORO field? if not, ORO sounds like just what you
need---and it's output by the CCM1 by default so you should already
have it on your history tapes.
it's defined as 0. for ocean, 1. for land, and 2. for sea ice.
if you are worried about the distinction between land and sea ice,
you can use the ccm processor to make a derived field where you've
set all the sea ice to either land or ocean. processor docs are
freely available from the ncar gopher and web.
good luck,
charlie
