Please consider the following comments:

Regarding the referee's comment: P. 2, L. 24 and many other places: check the references in brackets: often names of authors are put in 10 brackets, although the names are part of the sentence. An Example: “In (Hiranuma et al. , 2015), 17 online and offline . . . “
For improved readability, please change to: "In Hiranuma et al. (2015),..." although AMT standard formatting is not unambigous about this point.

Fig. 9: Is there a reason to display the y-axis on the right hand side? If not, please switch to left side standard.

Fig. 9: There seems to be an additional data set of small light blue data points right around the dark blue large data points of SIO AIS 6.0x10(-6) weight% and the FRIDGE (imm. freezing) data points. This data set was not included in the original Figure, (nor in Hiranuma et al.) and is not described in the legend. Please explain or correct.
