Dear authors,
following up on the reviews provided by the referees on the one hand, and your comments to their questions/concerns, I would like you to invite you to submit a revised version of your manuscript. Please consider carefully all comments/remarks made by the referees - especially also the statement made on the potential (additional) microbial source of n-alkanes. After submission of your revised manuscript, we will evaluate the further processing of your contribution.
I look forward to receiving your revised contribution.
Best regards,
Laurent Pfister
