Keep in mind when you are operating at neutral bouyancy that if you trimmed
to neutral bouyancy in salt water the pass into an estruary or across the
mouth of a river the changing density of the less salty water may cause
your submersible to dive.

Sure with the million other things to worry about this is not a big one
on the list but again you need to be aware of it. You just might end up
getting deeper than your sub is designed for.
