Examine Weddell-Scotia Confluence Waters #52

Closed DaniJonesOcean closed 2 years ago

From Mike:

The technique seems to do a decent job of identifying the Weddell-Scotia Confluence waters – these sit between the Weddell Gyre and the ACC, but are distinct from both since they also receive shelf waters from the tip of the Peninsula that sink down into intermediate depths. These seems to appear in Class 4 of your first classification, and Class 3 of your second cut… they are very interesting (and in some ways quite important) so if the classification can be well-defined for them, that would be very nice. They are marked by reduced stratification in intermediate depths.

Action: see if we can argue that this is a clear identification of the confluence waters

A little more:

The waters that spill off the Peninsula shelf sink down to a few hundred meters deep – the weakened stratification is clearest at about the level of the CDW, so, maybe 500m or so… but this process is also implicated in freshening the AABW that outflows across the South Scotia Ridge (only slightly, but noticeably), and that is deeper 1000-2000m….

As pointed out in another issue, we might want to distinguish these from the near-FRIS waters, or at least explore how the properties change with longitude.

Pretty much incorporated into the OSM22 presentation. Can explore more in the paper
