[Dimitris Menemenlis]

Alistair, here is a plot of cfl values for days 390-524 and also a
blow-up right before crash.

Model used to crash around day 410.  Minor fix to bathymetry (in middle
of tropical Pacific, see second figure) makes it run for an additional
100 days.

Chris and I tried a bunch of other things, changing vertical and
horizontal diffusivity and viscosity, adjusting biharmonic, and bottom
drag.  But none of them worked (except for reducing time step to 300 s,
which is not practical).

Haven't yet looked at what happens on day 523, but I suspect a similar,
bathymetry-caused crash.

Should I just keep fixing bathymetry?  Any better suggestions?

D.
