A tutorial for adding new diagnostics in COBALT is provided here (*add link*).
A tutorial for adding new diagnostics in COBALT is provided [here](https://github.com/NOAA-GFDL/CEFI-regional-MOM6/wiki/Instructions-for-Adding-a-New-Diagnostic-in-COBALT).
The "diagnostic table" controls which diagnostics are generated. The default ocean and sea ice diagnostics for CEFI's regional MOM6 simulations can be found *here*, while the default ocean biogeochemical diagnostics can be found [here](https://github.com/NOAA-GFDL/CEFI-regional-MOM6/blob/feature/diag_table_cleanup/xmls/NWA12/diag_tables/diag_table_CEFI_COBALT_default). The file begins by defining broad output categories across which the diagnostics will be organized (check `output file section`[here](https://cefi-regional-mom6.readthedocs.io/en/latest/InputsOutputs.html#file-section) for more details).
