Dear Author,

I refer to your manuscript XXX submitted for publication to Biogeosciences. First, apologies for such a belated decision. I was out of touch with email and only came back to the office today.

The discussion phase is now over and I encourage you to submit a version revised along the lines of your replies to the referees' comments.

Best regards,
Jean-Pierre Gattuso

Dear Author,

Thank you for submitting a revised version of your manuscript submitted to Biogeosciences, which can be accepted for publication after minor revision. When submitting the revised version, please let me know which of the changes were not implemented, if any, and why. This will speed up final acceptance.

I look forward to seeing this paper published and thank you for considering Biogeosciences to publish these very interesting results.

Best regards,

- The referees asked to report the size range. In your reply, you say that the size range is already reported, as mass. Mass is not size! I appreciate that some sizes are not available but you could provide the measurements you have (length or diameter, depending on the shape of the species considered).
- I wonder how the percent saturation was calculated. For example, in the abstract you mention 130 µmol/kg is 10%. Using the standard equation of Garcia & Gordon (1992, L&O), the O2 saturation at S=35, T=5, depth=200 m, is 307.892 µmol/kg. Hence, 130 µmol/kg would correspond to 42% of the saturation value.
- Mention in section 2.2 that pH was measured on the total scale
- 224 and elsewhere: always use the subscript "T" when an absolute pH value is given, including in the heading of Table 2. The heading of that table should also provide the unit for temperature.
- aAbreviate "hours by "h"
- 272: ranged between 15 and 50 ml ... and 8 to 20 ml (similar changes needed line 323)
- 337-338: the symbol for mole is "mol", not "M". But in this sentence mole could be spelled out.
- 337: indicate for which species Mayzaud reported this respiratory quotient of 0.8.
- Please list citations chronologically throughout the manuscript.
- References need to be formatted as described in the instructions to authors.
- Biogeosciences strongly promotes the full availability of the data sets reported in the papers that it publishes in order to facilitate future data comparison and compilation as well as meta-analysis. This can be achieved by uploading the data sets in an existing database and providing the link(s) in the paper. Alternatively, the data sets can be published, for free, alongside the paper as supplementary information. The ascii (or text) format is preferred for data and any format can be handled for movies, animations etc…
