Dear authors,
Your manuscript is significantly improved after the revision. It can be accepted after a few very minor changes. See the comments from the reviewer below.

The authors have greatly improved the manuscript compared to the original submission. The advantages of the LAB60 simulation over other existing high-resolution simulations of the Labrador Sea have been made clear. Additional and revised text, figures and diagrams address the comments made by the reviewers before and thus there are only few remaining issues to be solved before publication as outlined below in the Specific Comments.

Specific Comments
ll. 11-12: This sentence is not really more clear than before. It still gives the impression that your regional configuration is set up within the Labrador Sea and the nests are implemented therein.
ll. 14-16: In the author response you state that you changed this sentence, however it is identical to the original manuscript.
l. 168: ''with'' should probably be ''and''.
l. 194: ''configuration'' should be ''configurations''.
l. 283: ''LS60'' should be ''LAB60''.
l. 352: ''match far closer'' should be ''are closer'' or ''match better''.
l. 363: ''most'' should be ''largest''.
ll. 369-372: In this paragraph you could mention that only data from one cruise is used. Otherwise on l. 372 ''during this cruise'' the reader does not know which cruise is meant.
l. 383: At this point I suggest to clarify that you refer to exchange with the interior basin/central Labrador Sea.
l. 698: It seems like the in Fig. 7, the titles for (c) and (d) are wrong. The upper panel should be Ring A and the lower panel Ring B.

Dear authors,
I would suggest to rewrite the sentence in the abstract that you changed during the last revision. Such as: "Our regional configuration spans the full North Atlantic and Arctic, while the high resolution is only applied in smaller nested domains within the North Atlantic and Labrador Sea. Using the nesting reduces computational costs and allows for a long simulation from ..."
