[ecco-support] ECCO Mixed Layer Depths criteria

[Martha Buckley]

Thanks for pointing this out Dimitris. Is this because the variable nature
of the density criteria is based on the thermal expansion coefficient, so
one choses too small of a threshold in these regions?  I guess using a
variable density criteria is supposed to help remove deep biases in cold
regions, but if it messes up regions that have a halocline, this isn't
desirable.  What do you recommend using as a MLD criteria in polar regions?
thanks,
Martha
