Dear authors,

Thank you for your detailed responses to reviewer’s comments.
I have gone over the responses to those reviews and believe that a publishable manuscript will come out after your revision. Please add the nifH data in the results section (not in the supplementary information) in the way you suggest “total diazotrophs”,”total UCYN” and “total filamentous”. Please also add a brief section in the Methods explaining how these data were generated and refer to the original paper for details.
More generally, to avoid the gap identified by the reviewers between the methods, results and discussion, please also add a section in the Methods explaining briefly how the biogeochemical data that are used in your paper for interpretation were generated and also refer to original papers for more details.

Finally, please incorporate in your revised manuscript the changes and/or precisions requested by the reviewers.

You are now invited to upload a revised version of the manuscript. Please provide a version of your manuscript under ‘track-change’ mode and one with accepted modifications.

Sincerely,

S. Bonnet

Dear Authors,
Based on the 2 Referee reports (I could not get the third one) and my own reading of your revised manuscript and responses to the Reviewers' comments, I am pleased to accept your manuscript for publication in Biogeosciences, assuming you will take into account the minor comments raised by Reviewer #2 attached.
Sincerely,
Sophie Bonnet
