Survey and Sequence Strategies for Full‐3D Electrical Resistivity Tomography in Archaeological Sites: A Case Study on a Domus of the Roman Town of Augusta Bagiennorum (NW Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Preliminary geophysical investigations are a cost‐effective and efficient way to screen archaeological sites and locate buried structures. Ground‐penetrating radar (GPR) is one of the most widely used methods for archaeological prospection, but in some sites, it cannot be employed effectively due to the presence of clay or other electrically ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.
