Dear Luiz,

My apologies for the delay in handling the revised version of your ms. Thank you for the very detailed replies to the points raised by the two reviewers, and the additional information provided. Based on the comments and evaluation of both reviewers, your manuscript clearly dicusses a very nice dataset and has potential as a Biogeosciences paper - both reviewers were generally positive but raised a number of major and minor comments which - based on my own reading and your replies - appear feasible to address. I therefore recommend submitting a revised version of your manuscript, which will be re-evaluated by at least one of the original reviewers.

Do not hesitate to contact me in case you have specific questions.

With best regards
Steven Bouillon

Dear Luiz,

Thank you for your revised version and author replies, which have now been reviewed by one of the original reviewers. I agree with their evaluation that you have adequately addressed the earlier comments, and I’m pleased to accept your revised version for publication in Biogeosciences. I have provided a list of textual corrections separately, please address these before uploading your final manuscript files.

With best regards
Steven Bouillon
