Dear Dr. Freitas and co-authors,

The revised version of your manuscript has been evaluated by the reviewer. She/he is satisfied with your revisions and finds that the manuscript has been greatly improved.

I am then pleased to accept your paper for publication in Biogeosciences providing that you address the last comment of the reviewer:

"The various rates of reaction are represented as Rj (Equation 1 and Table 3), rn (Equation 9 and Table S4) and Cox (Equation 4). I think these divergent symbols for quantities that appear to be dynamically similar can still be a cause of confusion, e.g., C is also concentration in Equation 1. It all seems unnecessary. Further, why use Cox,total for a flux if JOM,out is also the same flux? Wouldn’t one symbol (J) be enough?"

I thank you so much for your efforts during the reviewing process.

Kind regards,

Marilaure Grégoire
