Dear Drs. Hoffmann/Kirchlechner/Langer:

Thank you for submitting this paper to Biogeosciences. I have read your revision and your rebuttal and I am happy to inform you that your paper is now accepted for publication in Biogeosciences.

While reading, I identified a few points of attention:

1) The author list: you state that the first three authors contributed equally. What does that mean? each 1%? I doubt. I do understand why you do this, but please then use your author contribution statement (that you have) to specify the role of each author and the % contribution.

2) p. 2, line 2: ..correlation of these parameters....
3) p. 3, line 5 from bottom: ... BSE imaging were used.....
4) p. 6, middle of page: you present dynamic viscosity and gravity in meter units why not density as well in kg m-3.

5) Figure 6 and 7. Why don't you combine them as Fig. 6a and 6b. Moreover, in the text you cite Fig. 7a and 7b, while there is only one figure 7. Please check and correct the last part of your manuscript for consistency in this respect.


With best regards,

Jack Middelburg
Editor of Biogeosciences
