Dear Dr. Lachkar and co-authors,

I have read your answers to the comments of both reviewers. Based on that I invite you to submit a revised manuscript prepared according to the modifications underlined in your response and outlining the changes made. Please note that your revised work will be sent for another round of reviews.

Thank you so much for your efforts,

Kind regards,

Dear Dr. Lachkar and co-authors,

The two reviewers that have evaluated the first version of your manuscript have provided their feedbacks on the revised version. Both of them underline the efforts you made for answering their concerns. One of them has still minor concerns. Based on that, I recommend acceptation of your manuscript with minor revisions. Please submit a revised version considering the comments of reviewer #2.

I thank you so much for your efforts,

Kind regards,

Marilaure Grégoire

Dear Dr. Lachkar and co-authors,

I have read the answers you have provided to the remaining comments of the reviewers and I have found that you have successfully addressed the last concerns. Then, I am pleased to accept your paper for publication in Biogeosciences.

Many thanks for your efforts during the reviewing process,

Kind regards,
Marilaure Grégoire
