Distributed Self‐Potential Acquisition for Detecting Seepage in River Embankments

Self-potential (SP) methods are widely used for investigating electrokinetic processes associated with subsurface fluid flow in embankments and levee systems. However, conventional SP surveys often rely on fixed reference electrodes and static acquisition geometries, which can limit their applicability for dynamic monitoring and rapid field deployment. This study investigates the potential of alternative SP acquisition strategies to monitor electrokinetic variability under field conditions wh...

Has the fire weather index emerged? Insights from global and regional climate models

Wildfires are expected to become more intense due to global warming. This change will significantly affect ecosystems and communities. We examine when and where fire weather conditions go beyond natural variability by using the Canadian Fire Weather Index (FWI). We analyze data from CORDEX-CORE and EURO-CORDEX regional simulations, along with CMIP5 and CMIP6 global models, under the RCP8.5 and SSP5-8.5 scenarios. The study spans from 1980 to 2099 and focuses on Global Warming Levels (GWLs) ra...

Marine Fiber-Optic Distributed Acoustic Sensing (DAS) for Monitoring Natural CO2 Emissions: A Case Study from Panarea (Aeolian Islands, Italy)

Featured Application: This study highlights marine Distributed Acoustic Sensing (DAS) as a low-impact, spatially continuous technology for monitoring sub-seabed fluid and gas migration. In volcanic and hydrothermal settings, DAS enables long-term observation of degassing processes, providing high temporal resolution that complements geochemical and visual surveys. Furthermore, its sensitivity to bubble-related acoustic signals makes it a viable tool for offshore Carbon Capture and Storage (CC...

Surface pCO2 and hydrography in the dense water formation area of the southern Adriatic

The rising CO2 concentration in the atmosphere leads to an increase in CO2 uptake by the ocean and to significant changes in seawater chemistry. These changes, in turn, exert profound effects on marine ecosystems across multiple trophic levels. The Mediterranean Sea is considered a hotspot for climate change. Despite such relevance, observations and studies on its carbonate system remain limited, especially in regions that play a crucial role in regulating air-sea CO2 exchange such as interme...

Contrasting behaviour in geogenic degassing along an active segment of the East Anatolian fault zone (Türkiye)

Seismically active areas have long been recognised as hotspots of geogenic degassing. The present study investigated the Osmaniye Fault which belongs to the East Anatolian Fault Zone (EAFZ). Although EAFZ has been recently (February 2023) hit by the destructive Kahramanmaraş earthquake, the studied segment was not involved and is still accumulating stress. Three areas along this structure were selected with gas samples collected and analysed for their chemical and isotope compositions. Extens...
