The upwelling occurs in the gyre interior, as expected. It also seems to be concentrated along and south of the SBDY, which does roughly correspond with the class thought to be more affected by mixing between CDW and WW. Can we interpret this as "upwelling of CDW"? So that the CDW is brought into contact with the WW, encouraged by sea ice formation, brine rejection, and mixing?

(The mixing signal isn't so clear, as discussed elsewhere, but that could be a result of how strong the EKE signal is within the ACC)

Note the concentrated values along the coast. If they are trustworthy, that may be evidence of ventilation, consistent with our interpretation of the class that is more affected by ventilation.

Will write more about this in the paper. I'll close this issue and keep it as a reference.
