Dear Drs. Herrmann, Zeppenfeld and co-authors,

Thank you for the resubmission of your manuscript. I am satisfied with your response to the comments by the referees. The manuscript can now be published in Ocean Science. However, before final submission, please account for the technical comments that I have listed below.

L23 has the potential to contribute (instead of: potentially contributes)
L24 in future studies (instead of: during further research studies)

L117 for the biases described above. (instead of: for the described biases.)

L117 I suggest: With a low need of consumables, we will be able to analyze … (instead of: This method with a low need of consumables allows the analysis of…)

L135 psu is not an accepted unit. Practical salinity is dimensionless. Please use: with salinities of 10, 20, 30 and 40 on the practical salinity scale.

L153 consists
I suggest writing this whole section §2.3 in the present tense because it is the always valid description of the method and equipment.

L239-240 change to: … sea salt solutions (with salinities of 10, 20, 30 and 40).
L241 and the averaged mass at 0 min. (at instead of: after)?

L285 delete PSU. I suggest to write in parentheses (S=40)

Figure 2 Please change the label on the y-axis into something like practical salinity, or salinity on the practical salinity scale, but do not use a unit. Delete psu in the caption.

L292, 294 delete PSU
L322 delete PSU

L327 formula (1)
L330 Please just use (1) for the number of the equation

L340 delete PSU
Figure 3 Please remove PSU. In the box one could write S=10 etc.

L380 was recovered (not: could be recovered)
L383 “which could represent PCCHO” I think this does not say what the authors want to say. I suggest: which could pass off as PCCHO

L399-400 “The similarity of the equality line and the regression line (R2=0.89) using all sugar data indicate a good overall agreement between both methods.” I think that this is a strange way of saying that the methods compare fairly well. You do not need the equality line. It suffices to write that the slope between the two is 0.81.

Figure 5 caption: “Chromatograms of a) full chromatogram of …” This is not correct. I suggest: a) full chromatogram of standard solution 100 µg ·L1. Chromatograms of b-e) neutral sugars and ..,

L534 delete strange symbols and check reference for correctness
L581 volume and pages missing
L636 please use initials of authors
