Boxes indicate state variables, and solid arrows represent fluxes between state variables; dashed lines indicate that the rate of change of one state variable is calculated proportionately to another. Colors indicate the base element for each state variable, with blue, green, pink, orange, and gray representing nitrogen, phosphorous, silicon, iron, and carbon, respectively. State variable boxes are positioned vertically based on functional role, indicating whether the functional group includes producers (and within that, subcategories of nitrogen fixers, Si-users, and CaCO3-users), consumers, or detritus. Horizontal position indicates the approximate mean size of the cells/bodies/particles represented by each state variable.

Orange labels represent components that scatter or absorb light.
it is my understanding that Bling is simpler than WOMBAT or at least would not be an improvement on WOMBAT. COBALT is much more complex and could be a next step forward if computational resources allow
Yes, Bling is simple and parameterises productivity and export, it doesn’t even carry phyto-/zoo- plankton tracers (see schematic above).
COBALT or TOPAZ have interesting new capabilities. While GFDL versions of MOM6 are being tested, it should be straight forward to turn these tracer packages on; there are test cases with prepared boundary conditions(?) (It will be more complicated once MOM6 is coupled to CICE#.)
