Dear Sophie,

Your manuscript has been evaluated by 4 outside reviewers, the majority of which were strongly supportive of publication. One reviewer was somewhat more critical. In your responses, you appear to have taken the comments of all reviewers into consideration.

Besides revisions in light of the reviewers comments, I note on Fig. 2, the individual panels do not specify the parameters- which would be useful to the reader.

Cheers,

Doug

Dear Sophie et al.

I thank you for your thoughtful and detailed revisions to the reviewers comments and am very pleased to recommend your paper for publication in Biogeosciences.

I concur strongly with the two reviewers that it is an important paper making a substantial contribution to our understanding of the spatial distributions of nitrogen fixation in the world's oceans in this vast but chronically understudies area.

Cheers,

Doug
