Special Issue Information

Dear Colleagues,

The revolution in sensor technology of the last two decades—from precision magnetometers on drones to high-resolution LIDAR and hyperspectral cameras on aircraft; broadband three-axis geophones in modern land and marine seismic surveys; distributed acoustic sensing (DAS) on borehole fiber-optic cables; mobile gravity, electromagnetic, and ground-penetrating radar arrays; and more—has brought a flood of new data to traditional fields of applied Earth science concerned with mapping Earth’s shallow crust to depths of a few kilometers. These data have been obtained in an effort not only to find and manage needed resources like groundwater, minerals, and hydrocarbons, but also to monitor the safe disposal of waste products of our modern economy, including CO2 and other greenhouse gases driving accelerated climate change.

The extraction of more and better information from the Big Data generated by modern sensors requires automation. That might be as simple as rules-based AI software to conduct quality control for existing workflows, or as complex as training neural networks to fully replace certain time-consuming tasks of data and image interpretation that are currently carried out by human experts.

The goal of this Special Issue of Geosciences is to assemble a collection of a dozen or more papers exploring the state-of-the-art in the automated processing and interpretation of the large, new datasets for applied Earth science made possible by modern sensors. Papers highlighting progress in individual fields are welcome, as well as those promoting new insights to be gained by studying data from integrated, multi-physics surveys.

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.

Understanding the mineralogy and geochemistry of the subsurface is key when assessing and exploring for mineral deposits. To achieve this goal, rapid acquisition and accurate interpretation of drill core data are essential. Hyperspectral shortwave infrared imaging is a rapid and non-destructive analytical method widely used in the minerals industry to map minerals with diagnostic features in core samples. In this paper, we present an automated method to interpret hyperspectral shortwave infrared data on drill core to decipher major felsic rock-forming minerals using supervised machine learning techniques for processing, masking, and extracting mineralogical and textural information. This study utilizes a co-registered training dataset that integrates hyperspectral data with quantitative scanning electron microscopy data instead of spectrum matching using a spectral library. Our methodology overcomes previous limitations in hyperspectral data interpretation for the full mineralogy (i.e., quartz and feldspar) caused by the need to identify spectral features of minerals; in particular, it detects the presence of minerals that are considered invisible in traditional shortwave infrared hyperspectral analysis.
