[MITgcm-support] [EXTERNAL] Calculating sea ice export

[Menemenlis, Dimitris (US 329B)]

(1) Does the "sIceLoad" diagnostic ("sea-ice loading (in Mass of ice+snow / area unit)") need to be multiplied by "SIarea" ("fractional ice-covered area [0-1]") in every grid cell, or does it already take this into account?

It already takes this into account.  No need to multiply by SIarea


(2) I'm realizing that it's perhaps incorrect to use the ocean model's meridional velocity in the surface layer in this calculation, since for example wind can move sea ice too. Should I instead be using the "SIvice" diagnostic ("SEAICE merid. ice velocity, >0 form South to North")? Does this give the net movement of sea ice from both winds and ocean currents?

You need to use SIvice, which gives net movement of sea ice
