Hi Martha, I don’t remember exactly why it is that we run into trouble with the Kara MLD definition in polar regions.
<div class="">As you say below, .8 deg C corresponds to a much smaller (factor of 5 to 10) deltaRho in ice-covered oceans,</div>
<div class="">and maybe that’s what caused trouble.</div>

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?</span>
