Caldera’s Breathing: Poroelastic Ground Deformation at Campi Flegrei (Italy)

Frontiers in Earth Science, 2021
Ground deformation at Campi Flegrei has fuelled a long-term scientific debate about its driving mechanism and its significance in hazard assessment. In an active volcanic system hosting a wide hydrothermal circulation, both magmatic and hydrothermal ...

Seafloor hydrothermal systems [PDF]

Journal of Geophysical Research: Solid Earth, 1995
The discovery of seafloor hydrothermal systems approximately two decades ago has led to a major reassessment of the Earth's thermal and geochemical budgets and has revolutionized our understanding of biological processes. This review traces the development of the study of seafloor hydrothermal systems from the indirect evidence provided by conductive ...

Competitive Behavior of Hydroelectric Power Plants under Uncertainty in Spot Market

Energies, 2022
This article aims to analyze agents’ behavior in a competitive hydrothermal energy market. The idea is to investigate how much the day-to-day behavior of the market can be different from the predictions presented by cost-based models because of the risk ...

Abiotic Methane Generation via CO2 Hydrogenation With Natural Chromitite Under Hydrothermal Conditions

Geochemistry, Geophysics, Geosystems, 2021
In modern continental serpentinization systems and ultramafic rock‐hosted sub‐seafloor hydrothermal systems, it is believed that chromitite plays an important role in abiotic hydrocarbon generation.

Comparative metagenomics at Solfatara and Pisciarelli hydrothermal systems in Italy reveal that ecological differences across substrates are not ubiquitous

Frontiers in Microbiology, 2023
IntroductionContinental hydrothermal systems (CHSs) are geochemically complex, and they support microbial communities that vary across substrates. However, our understanding of these variations across the complete range of substrates in CHS is limited ...

MARHYS (MARine HYdrothermal Solutions) Database: A Global Compilation of Marine Hydrothermal Vent Fluid, End Member, and Seawater Compositions

Geochemistry, Geophysics, Geosystems, 2020
We introduce a database of hydrothermal vent fluid compositions extracted from peer‐reviewed publications. The database includes general fluid parameters (e.g., temperature, salinity, and pH) as well as major‐, minor‐, and trace‐element concentrations ...

Numerical Modeling of Hydrothermal System Circulation Beneath Asal Rift, Republic of Djibouti

Energies, 2022
Asal rift is an aerial rift segment resulting from the westward propagation of the Aden ridge into the Afar Depression. Geothermal manifestations such as hot springs and fumaroles, fault creep, conductivity anomaly, and high geothermal gradient were ...

Carbon Oxidation State in Microbial Polar Lipids Suggests Adaptation to Hot Spring Temperature and Redox Gradients

Frontiers in Microbiology, 2020
The influence of oxidation-reduction (redox) potential on the expression of biomolecules is a topic of ongoing exploration in geobiology. In this study, we investigate the novel possibility that structures and compositions of lipids produced by microbial
