The article is appropriate to support the publication of the dataset. The authors used standard methods, well described and referenced. The data presented represent a novelty in the field, so that the potential application and correlation with direct investigations and researches conducted in the area appears obvious to the terrestrial permafrost scientific community. The dataset is competitive and accessible via the given Zenodo identifier. The state of the art in data collection and processing is adequately described. The dataset is significant, useful and complete. The dataset is usable in its current format and size. Adequate space is used to describe the data, their organisation and possible processing, including appropriate examples. The overall structure of the paper is well organised and clear. A minor revision of the language is suggested. About uniqueness, costly data sets such the one supported by the authors are not easily replicable for financial reasons. Variations in permafrost conditions due to climate change are strongly influencing Arctic hydrology, although the implications are not yet well understood. Such a dataset could help to better frame the high quality research area around Ny-Ålesund and open the way to advanced multidisciplinary knowledge. Some minor revisions are suggested in the Supplement document attached.
