Experimental evidence of electrification processes at the 2009 LAquila earthquake mainshock [PDF]

open access: yes, 2015
Two types of coseismic magnetic field events are simultaneously observed: transient offset events and magnetic field signal that occurred at the destructive, Mw6.1 LAquila earthquake (EQ) mainshock. The offset event, conventionally interpreted as a signature of piezomagnetic effects, however could not be ascribed as such.

The effects of extreme weather on rural transportation infrastructure and crop prices along the Lower Mississippi River

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices.

Geophysical tomography in engineering geology: an overview [PDF]

open access: yesThe Open Geology Journal, Vol. 3, 30-38, 2009, 2005
An overview of the tomographic interpretation method in engineering geophysics is presented, considering the two approaches of the deterministic tomography inversion, developed for rock elasticity analysis, and the probability tomography imaging developed in the domain of potential fields methods.

Semi-Automated Segmentation of Geoscientific Data Using Superpixels [PDF]

open access: yesarXiv, 2023
Geological processes determine the distribution of resources such as critical minerals, water, and geothermal energy. However, direct observation of geology is often prevented by surface cover such as overburden or vegetation. In such cases, remote and in-situ surveys are frequently conducted to collect physical measurements of the earth indicative of ...

Description and Understanding of Complex Fault Block Reservoir Geology

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Reservoir description is an important step in oilfield development. Before mining, using various technical means to analyze and study oilfield structure can achieve the purpose of fully understanding the reservoir and provide theoretical basis for reservoir development.

Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.
