Seismo‐Acoustic Evidence for Meteoric Water Modulation of Hydrothermal Fluid Discharge

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Deciphering the signal of external processes on active hydrothermal dynamics represents a critical challenge in understanding volcanic unrest. At the Pisciarelli hydrothermal site, located within the densely populated Campi Flegrei caldera (Italy), we investigate the role of meteoric water influx in modulating shallow hydrothermal fluid ...

Dynamic Models of Magma Storage Within a Damaging, Strain‐Softening Crust and Their Application to Sierra‐Negra's Pre‐Eruptive Inflation Pattern

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Prior to its 2005 and 2018 eruptions Sierra Negra's caldera displayed decades‐long inflation characterized by successive transient uplifts culminating in accelerating uplifts in the 1–2 years prior to each eruption. These observations motivated the question: can these transient uplifts be explained by internal dynamics of the magma system ...

Integrating GNSS and Hydrological Data to Understand Seasonal Microseismicity at La Soufrière de Guadeloupe

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract La Soufrière de Guadeloupe volcano exhibits microseismic activity dominated by volcano‐tectonic repeaters, mainly occurring in swarms clustered in a sub‐vertical conduit beneath the Tarissan acid lake (TAS) at depths less than 800 m. Following the April 2018 earthquake (Mlv 4.1), which likely damaged the dome, swarms intensified and show ...

Natural Products from Marine Heterobranchs: an Overview of Recent Results

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2019
Heterobranchs are a fascinating group of marine mollusks that are recognized as an important source of bioactive natural products. Often, these molecules, which are either selected from the diet or de novo biosynthesized by the mollusks, play a ...

Fermentation Technologies for the Optimization of Marine Microbial Exopolysaccharide Production

Marine Drugs, 2014
In the last decades, research has focused on the capabilities of microbes to secrete exopolysaccharides (EPS), because these polymers differ from the commercial ones derived essentially from plants or algae in their numerous valuable qualities.

Long Unrest (2007–2025) at Laguna del Maule: Linking Strain Field and Seismicity From GNSS and Seismic Data

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Laguna del Maule volcanic field in Chile has been uplifting at exceptional rates since 2007, offering a unique opportunity to examine the interplay between crustal deformation and magma dynamics. To understand this relationship, we integrate GNSS with local seismic observations from 2013 to 2024 to model the reservoir strain field ...

Chemical and Pharmacological Prospection of the Ascidian Cystodytes dellechiajei

Marine Drugs
Marine invertebrates are a traditional source of natural products with relevant biological properties. Tunicates are soft-bodied, solitary or colonial, sessile organisms that provide compounds unique in their structure and activity.
