Dear authors,

Your TCD manuscript "Quantifying spatiotemporal variability of ice algal blooms and the impact on surface albedo in southwest Greenland" received two constructive reviews where both reviewers identified methodological issues and questions, which you already partly clarified in your author comments.

Now I would like to ask you to upload a revised version of the manuscript together with an author's response where you clearly address the comments of the reviewers. In this revised version I think it is specially important to address the topic of sensitivity of the 2BDA methods to changes in dust, ice properties, etc. and this may even include this sensitivity in your results (and not only discussion).

Best regards,
Stef

Dear Shujie Wang and co-authors,

Your revised TCD manuscript "Quantifying spatiotemporal variability of ice algal blooms and the impact on surface albedo in southwest Greenland" [tc-2019-226] has been seen again by both reviewers who both recommend that your manuscript can be accepted subject to minor revisions.

Before final acceptance, however, I recommend to address the comments raised by both reviewers. This includes the minor textual comments of reviewer 1&2, but also the important point raised by reviewer 2 regarding quantifying cell numbers.

When submitting revised materials, may I ask to include an Author's Response with a point-by-point response to the reviewers' comments.

Thank you again for submitting to The Cryosphere. We look forward to receiving your revision.

Sincerely yours,
Stef Lhermitte
