Dear Dr. Ohashi and co-authors,

Thank you for the resubmission of your manuscript. I am generally satisfied with the changes you made as a response to the reviews. Below my final comments and suggestions are listed. Please prepare your final submission for publication in Ocean Science.

P1, L21 suggests instead of indicates

P1, L40 “The plumes have higher fraction of subglacial discharge than those in the deep fjords due to greater entrainment of ambient water.” I am a little confused by this sentence. I think you mean “The plumes of shallow fjords have a higher fraction of subglacial discharge”, but this cannot be caused by the greater entrainment of ambient water; a greater entrainment of ambient water would tend to reduce the fraction of subglacial discharge, right? Please explain and correct, if necessary.

P2, L24 temporally instead of temporarily?
P2, L25 I think you mean: the impact of varying fjord stratification on the vertical distribution of outflowing plume water … ; or something similar. As it is now, it is not clear.

P2, L34-35 This sentence says exactly the same as the previous one. It should be deleted.

P3, L4 delete: exposing open ocean surface. It is self-evident that after melting there is open ocean water.

P3, L23 I think the notation 14D1-6 and 16D1-6 for all stations is not clear. Please modify, for example, to 14D1 to 14D6

P3, L27, L32 (and at other places in the text) Please do not use psu as a unit for salinity. This is not a unit. Salinity is a ratio and thus without physical unit. Alternatively, please indicate the salinity scale, for example Practical Salinity Scale.

P4, L27 specifically instead of significantly?
P4, L28 θ–S properties were similar …

P4, L36 delete: “The vertical structures of temperature were notably different between 2014 and 2016.” This info was already given earlier and again after this sentence.

P4, L38-39 “with a temperature of −0.8 °C in both observations.” It is not clear which observations are meant. Please modify wording.

P5, L13 “Salinity varied vertically between 2014 and 2016.” This can be deleted because this info is given in the next sentences.

P6, L2-3 “The results were similar for the other stations.” It is not clear to me which other results are meant here. Please explain and/or modify.

P6, L4-5 “The θ –S properties obtained in 2014 were closer to those of the AW core than the PW core (Figs. 7a and 7c), whereas they were more similar to the 5 PW core” This sentence does not make sense. Please correct.

P6, L7-9 “In both 2014 and 2016, near the PW core, the θ –S properties deviated slightly from the melt line and were located outside the meltwater quadrant, implying the influence of PW.” Especially the last part is not clear. If near the PW core, it is obvious that there is influence from the PW core. Please explain better what you mean.

P8, L12 Please modify: In Sect. 4.2, it was shown that high turbidity corresponded …

P8, L24-26 ” However, because the turbidity distribution at the fjord surface can be visually captured by satellites (Chu et al., 2012) and drones, it is easier to monitor the distribution of turbidity than to investigate the subglacial discharge fraction based on in situ observations.” I do not understand the intention of this sentence. It is easier indeed, but only qualitative estimations are possible (much additional info is missing). You just showed that your method can provide quantitative info. So this is about different things.

P8, L27 “This emphasizes the importance of turbidity measurements to better understand the subglacial plume behavior.” I think this sentence is superfluous, considering all info given before.

P9, L39-40 “The available excess heat of up to 0.9 °C …” Heat is not the same as temperature. Please be accurate in writing.

Figure 1 It is not clear what the location is of station 14 (blue) and station 16 (red) outside the fjord. In green it also says in the right corner of panel (b) St.16D6. What does that mean? Is St.16 the same as D6? Please clarify. I think the notation St.14 and St.16 is misleading. The first thing that comes to mind when reading this is station 14 and station 16, whereas you mean all stations in 2014 and in 2016, respectively. St.16D6 is one station indeed, which is fine as notation. Please change the notations for avoiding confusion.

Figure 2 Please do not use psu for salinity on the axes. In the caption: diagram

Figure 3 The figures in these panels are not vertical profiles (which are diagrams with depth on the y-axis against the concentration). They are called contour plots or (hydrographic/temperature) sections.

Figure 7 Please indicate in the figure, or describe in the caption, the meltwater quadrant.

Figure B1 Same as Figure 3: These are not vertical profiles

Dear Dr. Ohashi and co-authors,

Thank you for resubmission of you manuscript and accounting for all the comments. I have one comment left. Please correct this before final submission.

Page 3, line 27 with regard to the notation of salinity I suggest: 0.01 on the practical salinity scale
In all other cases in the manuscript, where you give a salinity, you do not need to add PSS.

Thank you and best wishes
Mario Hoppema
