Dear Perez-de-Lis et al.,

As you can see from the posted comments both reviewers found your study of interest and suitable for publication in Biogeosciences if their concerns can be addressed. I would ask you to pay careful attention to the comments of both reviewers when revising your manuscript, and in particular use the comments of reviewer #1 to improve the discussion section and the comments of reviewer #2 to ensure that the results reported adequately reflect those of the analysis. Please submit your revised manuscript along with a detailed reply to the reviewers' comments.

Best wishes,
Trevor F. Keenan

Dear authors,

Thank you for your detailed revisions in response to the reviewers' comments. You manuscript is much improved and I am happy to say we can now accept it for publication in Biogeosciences. I would ask however that you revise the manuscript for the proper use of English before submitting the final version, as I noticed some grammatical errors in the text (see examples below).

Best wishes,

Trevor F. Keenan
