This MS is a very nice description of the field data and analyses of the collected samples.

It is a pity though that data of water turbidly and fluorescence collected by WET Labs ECO-AFL/FL are not analyzed and described. I believe reported increase of the DOC/POC values at the depth could be nicely connected to the turbidity profiles.

I believe this MS can be published after minor revision after fixing a few remarks below.

Ln 374: should it be ‘easternmost’?

Fig. 5: I would suggest to use non-linear depth axis (as in Fig. 3) to better illustrate the upper photic layer.

Fig.6: Edit units notation in the caption (i.e. L^-1, not L-1)

Ln 421-422: Cold be that increase of DOC & POC be related to the bottom nepheloid layer? Are there any comparison with the turbidity records?

Ln 441: Looks lie St. 46 is located at the westernmost end of the transect (as mentioned in Ln 447). Please check and correct.

Ln 465-466: I would say that Sts 20 and 30 are central (as it is referred to in Ln 481), not easternmost. Please check and correct.

Ln 602: Consider replace ‘during’ with ‘along’

Ln 606: consider replace ‘lighter’ with ‘lower’

The authors present a very comprehensive hydrographic biogeochemical and biological dataset from a cross-section at 75°N from the East Greenland Shelf to the Barents Sea shelf in late summer 2021. The data set is very extensive with the various parameters that were investigated and allows an insight into the interrelationships of the biological ecosystem during this time phase. 

I think the manuscript can be accepted after a view minor change as following:

Line 42/43: Sentence unclear please rephrase

Line 212: How many replicates were taken? How was the spatial variability of the POC on the filter handled?

Line 222 Could you comment on using (HDPE) bottles, I thought DOC should be in pe-combusted glass vails?

Line 247 Please give µm units for polycarbonate membranes

Figure 5: Please use same y-scale as for Fig 3 for better visibility of the biological relevant surface data.  

Figure 6 & 14: Please improve the quality of the  figures and  hange the order in West -East, as done for all other figures

Figure 9: Integrated contribution again 0-100m?

Figure 10: Integrated values again 0-100m?

Figure 14: change unit notation to: μL O₂ h^-1 L^-1
