You would almost have to redo the scenery in the areas with ocean 
coverage to include the ocean floor elevation, then draw the ocean as a 
seperate layer that can be moved up and down exposing more or less of 
the terrain.

The trick maybe to find a good sea floor elevation database that is 
reasonably compatible with SRTM, and mesh the two data sets seamlessly.
