This is a nicely-scoped proposal, and one I’d be interested in contributing to. Probably good to be careful about expanding the scope too far, but it would be great to include model validation against oxygen observations (e.g. WOA).
A logistical question I have (not related only to this project) is how you’re envisioning collaboration working across the different sites. Would it make most sense for folks to work in project groups located at a single site, or do you think it would work to have people working on this project from multiple locations?
