Potential Geophysical Field Modeling as a Power Tool of the Earth Knowledge

Dear Colleagues,

Potential geophysical fields—gravity, magnetic and thermal—are now recognized as powerful instruments for studying the deep structure of the Earth. For all three fields, giant data arrays were accomplished (many tens of millions). The datasets began to increase with the development of different satellite missions (for gravity and magnetics). The developed methodology of retracking satellite gravity data to the sea surface and rugged land topography opens new horizons for gravity data processing and transformation. The enormous amounts of thermal data determined from deep and middle boreholes enable to image thermal regimes at these depths and to continue these calculations further down. Interactive gravity–magnetic, as well as thermal modelling, allow to constructing deep physical–geological models and correlate them with seismic, magnetotelluric, and other data. As shown the rich experience, such transformations as calculation of different derivatives, upward and downward continuation, searching for ring structures, calculation of entropy and informational parameters, nonlinear and self-adapting filtering, applications of different statistical and probabilistic operations, and other methods, can lead to increasing our knowledge about the buried structures of the Earth. Multilevel analyses of potential geophysical fields are of certain interest. Both single potential geophysical modeling and, especially, their different integrations are welcome.

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. Physics is an international peer-reviewed open access quarterly 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 1400 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.
