About the Journal

Aims and Scope
CGG publishes original research papers (no review papers, no research letters or short communications) covering a wide spectrum of earth science disciplines including structural geophysics, geodynamics, tectonics, near surface geophysics, applied and environmental geophysics, geomagnetism, gravimetry, seismology, paleo- and rock-magnetism, space weather, geodesy and geomatics, surveying engineering, hydrology, hydro-geophysics, atmospheric science, climatology. CGG favours manuscripts that contain methodological novelty. Papers with local or regional applications of standard methodology to new observed data are not disqualified, but will be considered upon the discretion of the section editor or handling editor by assessing the scientific contribution and the expected value for the readership of the journal and the scientific community.

Open Access and licensing:
CGG is a platinum/diamond Open Access e-journal (free to read, free to distribute, free for authors, no processing or publishing fees) published quarterly. CGG uses Creative Commons licensing (CC BY-NC-ND). The authors do retain their copyright in full. From 2009 to 2019 CGG was co-published by Sciendo/DeGruyter as Open Access under this license

Review Process:
Submitted manuscripts are reviewed by peer reviewers in a single blind review process (reviewers may waive their anonymity if they wish). Reviewers and editors must treat submitted manuscripts as confidential and must not upload any part of them into AI tools, as this could violate authors’ rights or data privacy regulations. Reviewers remain responsible for the accuracy and integrity of their assessments.

Similarity check (plagiarism):
Submitted manuscripts undergo similarity checks using iThenticate prior to review.

Use of AI:
CGG allows authors to use AI-based tools to summarize complex literature, identify research gaps, organize content, assist writing computational code, improve language, clarity and readability of manuscripts (ms). This must be done under author oversight and proper disclosure in terms of the statement on the use of AI at the end of the ms (among other statements before references). The statement should specify the tool used, its version, and the purpose of its use. AI may not replace human critical thinking, expertise, or evaluation. Authors remain fully responsible for the content of their work, including verifying the accuracy, comprehensiveness, and impartiality of any AI-generated output. AI-generated references or content must be carefully checked for errors or fabrication. AI tools should always be applied under author supervision, with careful review and editing of AI outputs. Authors must adhere to ethical standards, ensuring AI use does not introduce bias, factual errors, or violations of privacy and intellectual property.

Language:
The language of CGG is English. 

Publisher:
CGG is owned and published by the Earth Science Institute of the Slovak Academy of Sciences.

History:
CGG is the journal of the Earth Science Institute (ESI) of the Slovak Academy of Sciences (since July 2015), formerly of the Geophysical Institute of the SAS, which merged in July 2015 with the Geological Institute of the SAS to form the ESI SAS with two divisions (geology and geophysics). CGG is a successor of the journal Contribution of the Geophysical Institute of the SAS published by the institute (once per annum, ISSN 0586-4607) since 1969 and its associated “Series of Meteorology” (once per annum, ISBN 80-224-0187-0) since 1974. Since 1998 (Vol. 28) the CGG had been published in print as 4 issues per annum. Since 2009 the 4 issues are published also electronically as Open Access fulltexts. From 2009 to 2019 CGG has been co-published by Versita, DeGruyter (successor of Versita) and recently by Sciendo (of De Gruyter). In 2014 (Vol. 44) the print production stops and CGG becomes electronic only.
