Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)

Near Surface Geophysics, Volume 24, Issue 3, Page 262-288, June 2026.
Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

A Structured Review of Selenium Pollution in Global Aquatic Environments: Sources, Levels, and Co‐Pollutants

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Despite its nutritional and industrial significance, selenium (Se) is considered a pollutant in aquatic environments owing to its toxicity at elevated concentrations, which potentially cause environmental degradation and adverse health effects in humans and local biota.
