Icepack- BGC tracers output

I am trying to run Icepack with the BGC components but I can't see the output. I have the netcdf history format so I can see the output variables, which are working for the other snow tracers. I believe I have all the correct tracers turned on for the vertical zbgc layer (the tr_brine, z_tracers, solve_bgc, tr_BGC_Nit as mentioned by 2.9. Biogeochemistry — Icepack documentation) and the cpl_bgc is set to true in the input file. Additionally the z_bgc and z_brine tracers are set to 1 in the icepack settings file.

The model compiles and runs but I don't see any of the bgc tracers in the .nc output despite being defined in the diaginostics_bgc.F90.

Any help would be much appreciated!

The Icepack netcdf interface is very primitive. There is a big tracer array (trcr) that get dumped to the netcdf. If you check your log file, you will see the tracer numbers there. These are indices in the trcr array, or at least the value is one greater than the index in the netcdf array.

Thank you, I do indeed see the array. Is there any documentation to help discern and match the tracers with the numbers?

I have found a list of variables I think correspond in icepack_tracers.f90? However, I don't see any mention about the chlorophyll tracer, has this been removed?
