Hi Alistair,
sorry for my answer, but I'm currently at the WOCE YI Workshop in
Boulder.
Now to your questions:

I made some runs with the NA model, but I had to set very small
timesteps (60s).
After introducing the new biharmonic discretization I was able to
increase that to 120s and ran the global model at least a few days.
Because the timesteps were too small I skipped the lopped cells. You can
find some of my configurations at the (not actual) websites
http://www.ecco.ucsd.edu/internal/atl/ecco_atl6_test.html and
ecco_glo6_test.html).

The scripts and the html document are not up to date. But if you want I
cold correct these (I should always do that) and send you actual
versions.

I will do that after my return (or maybe earlier). Any certain
coordinates, parameters?
Ciao,
