Please upload a revised manuscript that addresses the changes outlined in the response letters and thank you for the careful responses to referee comments.

The authors conscientiously addressed referee comments and I thank them for that but I would appreciate if they gave the manuscript another careful read for accuracy noting as one example 'legate' instead of 'negate' in the abstract. I am also of the opinion that Figure 2 could be improved to avoid text overlaps in the figure and that the light green of Figure 3 would benefit from a more readable color. Please make these and any other changes that you see fit to improve the revision and I would be happy to consider it for publication in Biogeosciences.

Sincerely,
Paul C. Stoy
