[LibCF #QMO-280170]: libcf can't yet deliver geospatial coordinates from an ocean_s model, can it?

No, sorry, that capability is in the plans for libcf, but it hasn't yet been
implemented.  Our libcf guru, Ed, will give a talk next week at the GO-ESSP
meeting on what libcf can do now and what is planned for the next year.

Implementing an F90 interface to libcf has been a higher priority lately, due
to requests from some modelers.  Handling curvilinear coordinates sounds like
something we could get some help implementing from OOI-CI, as they have
informally mentioned developing some useful capabilities we both need 
rather than supplying resources directly ...
