Special Issue "Gas and Gas Hydrate in Permafrost"
A special issue of Geosciences (ISSN 2076-3263).
Deadline for manuscript submissions: closed (1 October 2018).
This Special Issue of Geosciences aims to gather original research articles and reviews, which are dedicated to the research of genesis, composition specifics, migration, and accumulation of the natural gas in permafrost, and the possibility of gas existing in gas-hydrate form under permafrost and subpermafrost conditions.
Permafrost occupies vast land territories of the northern latitudes and of the Arctic shelf. Its thickness can reach hundreds of meters. The existing data on permafrost gas content allow us to say that permafrost layers are a natural medium capable of accumulating significant volumes of gas. With this in mind, natural gas accumulations in permafrost can be considered as a promising unconventional source of hydrocarbons. On the other hand, sudden gas manifestation, and even gas emissions when drilling wells in permafrost strata, are associated with accumulation of intrapermafrost gas and gas hydrates, which poses potential geological hazards in the development of Arctic oil and gas fields under permafrost strata.
Special interest should also be paid to the ecological aspects of the presence of gas and gas hydrate accumulations in permafrost, primarily in the near-surface layers. For this, it is necessary to assess the greenhouse effect of the intrapermafrost gases, particularly methane, with the possible thawing of permafrost, especially on the Arctic shelf. Nevertheless, the gas component of permafrost remains poorly understood, despite obvious scientific and practical interest. 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:
- Genesis and composition of intrapermafrost gases
- Gas and gas hydrate accumulation in permafrost
- Gas emission from permafrost
- Dissociation of gas hydrate in permafrost
- Properties of frozen gas and gas hydrate saturated sediments
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.

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 papers will be 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 1000 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.
