I didn't mean to say that the "rotation" is an issue.

Just thought that your problem is an artifact of
diagnosted fields (and maybe just the "vector" fields).
Conceivably theses fields might
not be masked proprerly, and the "empty tiles" contain garbage.

Could you plot an ocean state variable, e.g. uvel at surface
Do the holes appear in the ocean state variables?
(sorry, maybe you did all this,
I didn't follow a lot of the conversation).

-p.
