Laboratory Heat Flux Estimates of Seawater Foam for Low Wind Speeds
Round 1
Reviewer 1 Report
This is paper is overall a well-written and interesting description of laboratory measurements of changes in heat flux due to seawater foam. The results are mostly clearly described and the discussion provides interpretations of the results using simple models. Below I have one question related to the discussion of the results along with several editorial comments.
The vertical profile of the air fraction in the water when foam is generated
from breaking waves will differ from the profile seen in the experiment using the diffuser at ~1m depth. I think the paper would benefit from some discussion of the impact of this difference on the results especially those shown in Figure 7.
The meaning of the phrase "end ranges of the measured conditions" in the Figure 3 caption is not clear. It would be better to specify what conditions apply to the different profile plots.
Figure 6 caption references panels (c) and (d) but those subpanels are not included in the manuscript.
Figure 7(c) caption contradicts symbol (dots and squares) meanings for the foam and foam free surface shown in the legend of the figure.
Does the phrase "increase more rapidly" used in the text describing Figure 8 results (both panels) refer to some time evolution not shown in the figures or is it just intended as another way of saying that foam-free surfaces have higher ΔTskin vs QE for foam-free and foam surfaces appear to be about the same in Figure 8(a)?
Figure 9(b) caption and text description reference relative humidity but the plot shows QE versus wind speed and air-sea temperature difference. Please explain.
The sentence on lines 379-381 needs to be edited for clarity.
Lines 392-394 refer to "air-phase temperature profiles in Figure 3" but Figure 3 shows wind speed profiles.
