[MITgcm-support] shelficeForcingS addition to boundary layer

[Madeline Miller]

Dear Martin/anyone familiar with the shelfice package,

A while back we added a diagnostic for the salt forcing from the ice shelf,
SHIForcS
where SHIForcS = shelficeForcingS*rUnit2mass (g/m^2/s).

I am adding a 3d tracer for the quantities added to gS in the "boundary
layer" and it looks like there is a discrepancy between our diagnostic and
what is actually being added to gS , but I am probably just confused so I
would be very happy if you could offer some clarification on the salt
addition scheme.
