Review of revised version of “Arctic Ocean outflow and glacier-ocean interaction modify water over the Wandel Sea shelf” by Dmitrenko etal.
I appreciate the improvements that were made in this revised version, and I only have a few remaining remarks and suggestions. My biggest problem that I have with this paper is to really understand the importance of the Wandel Sea for the Arctic Ocean outflow. While all the map-figures in the paper provide some valuable information, I feel that there is still one map missing that would introduce the region with an intermediate zoom. The way I read the paper, the Wandel Sea is a tiny glacial fjord system, but it really is more than that. Zooming in on the northeastern half of Greenland on the IBCAO map gives a nice bathymetric overview of the region. Figure 1 is too coarse to show that, and figures 2-4 are too detailed. Based on your data, you infer a certain circulation pattern on this shelf, which might justify that you summarize these findings in a map with sketched-out current vectors. This would help the reader to better understand the implications of the analyses. The paper implies that the region features a number of processes (glacier-ocean interaction, shelf-basin exchange, and is an advective pathway or the beginning of the East Greenland Coastal Current), which could be emphasized in the abstract and in the summary. I would encourage the authors to consider these points, but I leave that up to their discretion. In my opinion the paper’s relevance could be increased without too much additional work.
A few more minor points:
- Fig 8: label the lines with „T“, „S“ etc
- In my opinion, introductory sentences to following sections are not necessary (i.e. lies 398-400; 427-429)
- L461-472: What is the idea regarding Siberian shelves river water? Is the freshwater advected with the Transpolar Drift to the NE Greenland coast or are you assuming a detour of the river water through the Canada Basin? This part could use clarification
- L109: where is the ITP station on the map?
- L132: profiles that were collected
- L192: …which reveals or revealed… |
