Reviewer #1: Anonymous
This report has been routinely published for each JARE cruise. Therefore, no more major revisions are required.
I have only very minor comment:
1. Several technical terms are connected with a hyphen, such as macro-nutrient, fast-ice, pack-ice, sea-ice, multi-year.
I'm not sure that all such words need a hyphen.
2. Regarding '4. Data Records', it is better to show format of 'DATE'. e.g. DD/MM/YY

Reviewer #2: Anonymous
In this manuscript, the authors provide a dataset of water temperature, salinity, chlorophyll-a concentration,macronutrients (nitrate, nitrite, phosphate, and silicate), and zooplankton data collected at six stations in the sea-ice
region of Lützow-Holm Bay, off Syowa Station during the icebreaker Shirase JARE-58 cruise. The manuscript is well
written, and the dataset is appropriately provided. I recommend accepting the manuscript for publication in Polar Data
Journal after a few minor revisions, as listed below.

Authors Response:
Thank you very much for your e-mail concerning our manuscript together with the comments from the two reviewers.
We found several important points to be improved before acceptance on this Journal. We have made some minorchanges (in red), according to referee’s comments.

A: Several technical terms with a hyphen in this text are commonly used in scientific papers, and they have alreadybeen used in this Journal (e.g. Makabe et al. (2020), Shimada et al. (2020)).
2. Regarding '4. Data Records', it is better to show format of 'DATE'. e.g. DD/MM/YYLine 116: added the “(DD/MM/YYYY)” after “the sampling date”.

Resoponse to reviewer #2:

macronutrients (nitrate, nitrite, phosphate, and silicate), and zooplankton data collected at six stations in the sea-ice
region of Lützow-Holm Bay, off Syowa Station during the icebreaker Shirase JARE-58 cruise. The manuscript is well

3.3. Chlorophyll aLine 3: Change "300mL" to "300 mL"
Line 75: change “300mL” to “300 mL”.
Line 5: Please provide the product name and supplier of the membrane filter (pore size: 10 and 2 μm).
Line 77: added the “Whatman nuclepore” before “membrane filter (pore size: 10 and 2 μm)”.
4. Data Records
Line 1: Change "Salinity" to "salinity"Line 103: change “Salinity” to “salinity”.
5-2. Wet weight measurement
Line 7: How did you split samples into 1/2 to 1/32 aliquots?
Line 178: added the following sentence for clarify this pointed out.
“We used a Motoda box-type plankton sample splitter to subdivide a sample.”
Line 7: Change "<10mm" to "<10 mm"
Line 176: change “<10mm” to “<10 mm”.

We hope that our revisions will improve the manuscript to your agreement.
