Thank you for your submission to Biogeosciences. We received two reviews from highly qualified researchers in this field. Both agree that this MS addresses a topic of interest to Biogeosciences readers, but several corrections, edits, and suggestions for improvement were offered. I will be happy to consider a revised submission that substantively addresses these reviewer comments.

Based on the authors' responses to the reviewer comments in the MS discussion, it sounds as if the proposed revisions are likely to address the concerns raised. Thus, I invite you to submit a revised version of your MS that comprehensively addresses these reviewer comments as described in the Authors’ response to reviews. Please pay particular attention to addressing the reviewers' comments, and please be sure that the clarifications provided in the response to reviewers are also incorporated into the manuscript text. Finally, please clearly describe how the text was revised according to the reviewer comments when submitting your revised manuscript.

Thank you for these edits, and for your support of Biogeosciences.

Sincerely,

Michael N. Weintraub
