Gas and Gas Hydrates and their Interaction with Permafrost

Dear Colleagues,

This Special Issue of Geosciences aims to gather high-quality original research articles, reviews, and technical notes on the problem of gases in the permafrost domain, its forms, production, possibility of migration, and potential for the global environmental changes.

The problem of interaction between gases and permafrost has both fundamental and applied significance. On the one hand, permafrost is a huge potential pool of organic carbon that could potentially be involved in modern biogeochemical cycles. Biogenic gases trapped within some genetic types of frozen deposits are an important part of this pool, which can be instantly released into the atmosphere in the case of permafrost degradation. On the other hand, being an impermeable layer, permafrost affects the processes of gas migration and, thus, the accumulation of natural gas in deep geological strata. Another important aspect of this topic is that permafrost is an environment, where, due to cold temperature, gases can be found close to the ground surface in the form of clathrates, also known as gas hydrates, which can be considered as a significant source of carbohydrates.

Therefore, I would like to invite you to submit articles about your recent work, experimental research, or case studies, with respect to the above and/or the following topics:

• Gas hydrates
• Greenhouse gases in permafrost
• Production of the biogenic gases in terrestrial and aquatic systems in high latitudes
• Permafrost impact on the processes of gases migration in the lithosphere
• Influence of permafrost degradation on the greenhouse gases emission into the atmosphere

I also encourage you to send me a short abstract outlining the purpose of the research and the principal results obtained, in order to verify at an early stage if the contribution you intend to submit fits with the objectives of the Special Issue.

Dr. Alexander L. Kholodov
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
