The authors have made very considerable changes to the manuscript based on the comments of the reviewers. While two reviewers suggested they expand the discussion to cover additional aspects of the topic, I agree with the authors that this would make the paper even longer than it is now, and that as they are planning on writing a second paper that will cover these aspects, it is unnecessary.

I believe this paper will be very useful to members of the oceanographic community involved with air-sea interaction and the mixing of surface water into the deep ocean, and that it can be published as it stands.
