Dear Dr DeJong,
I'd like to thank you for responding to the referees' comments. Based on the recommendations from both reviewers, and on my reading of your responses to the comments, I will recommend that your manuscript is accepted for publication in Biogeosciences subject to minor revisions, basically after you incorporate in a revised version the several points raised by the referees and discussed in your responses.
Again, I'd like to thank you for submitting your best work in Biogeosciences,
Sincerely yours,
Laurent Bopp
