Dear Dr. Jurikova:

Thank you for submitting this paper to Biogeosciences. Your paper has been evaluated again by one of the referees and he suggested acceptance as it is . However, he did not enter it into the editorial system and I was only informed yesterday that there was a miscommunication between the referee and the editorial office. This being said, I have read the rebuttal and revised version and I am happy to inform you that your paper is now accepted for publication in Biogeosciences. However, while reading the manuscript I identified quite some issues that need (technical) correction:

L. 14, below or in, what do you mean here?
L. 26 seasonality is consistent with the small overall variation….. and also with the long residence of water in the reservoir.
p. 11-14:
Sequence of figure. Figure 5 is now cited before fig. 4. Please re-number figures in sequence of first citation. Accordingly, number 4 should become 5 and vice versa.
P. 13: Fig. 7 is cited on page 6, yet figure 6 has not yet been cited.
p. 15
L. 15-18 are unclear, please reformulate.
L. 28: of the latter is inferior
P. 16
L. 26: While a non-steady state model
p. 17
L. 7 are associated with each.
l. 14: should this not be figure 7 instead of 6?
p. 18
L. 5 our data are too limited
L. 27: any other approach
L. 29 well-characterised

I am looking forward seeing your paper in final form in print.

With best regards,

Jack Middelburg, Associate editor

Short summary

Life on Earth is directly or indirectly linked to primary production (PP), the quantification of which poses a challenge. In our study we use the oxygen isotopes and oxygen–argon ratios technique to estimate PP in situ. To date this method has been used to assess PP in the ocean and we expand on its application to freshwater systems. Providing that the physical structure of the water column is constrained, this method presents a powerful tracer for atmospheric vs. photosynthetic oxygen input.
