Matt, I am going to guess that free drift is probably a good estimate for most
of Southern Ocean, except close to coastlines.  I don't know what your A and B
numbers should be, they would depend on drag coefficients, etc.  Look for papers
by Miles McPhee on topic.  Although most of his work is for Arctic Ocean, I
think that his estimates over first year ice should be applicable for Southern
Ocean.

Not true anymore.  Martin's magic C-grid formulation makes ice-affected ocean 
stress possible.  We need to write it up.  Apparently it's a big deal for 
sea-ice models.  Trying to iron out residual problems with growth, etc., first.

Cheers, D.
