Reviewer 1 Report
The manuscript should be significantly improved before publication. The English should be extensively polished. All sections of the manuscript require restructuring and reworking. Methods section should be extended to cover the details for the headspace technique and chamber method for flux calculation from boreholes. Other comments are in the attached pdf file.

Reviewer 2 Report
This paper reports on observation results of methane gas from permafrost and natural gas hydrate within. The topic studying in this paper is timely. However, there are several minor points to be considered before publication. After the corrections considering following points, the paper would be worth publishing.
1) Location map of the samples used is useful for better understanding of potential readers.
2) More detailed captions and instructions on Figs.1-6 are necessary.
3) It is necessary to add reference numbers within the text of manuscript.

Reviewer 3 Report
The manuscript provides only experimental measurement. No extensive analysis is done based on the measurement. The manuscript looks like experimental report, not a scientific paper.
