Effect of the vintage year on strontium isotopic ratio (87Sr/86Sr) of wines: a Portuguese case study

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 3, Page 1940-1947, February 2026.
Abstract BACKGROUND Currently, there is a growing need for wine authenticity tools to face the global wine market and deal with adulteration cases. Stable isotope analyses, recognized by the Organization of Vine and Wine as a tool for detecting authenticity fraud, form the basis of the European Wine Databank, which faces limitations concerning the ...

Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...

Interpreting Changes in Global Methane Budget in a Chemistry‐Climate Model Constrained With Methane and Isotopic Observations

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract The continuous increase in atmospheric methane (CH4) concentrations over the past few decades has become a major concern due to its strong role as a greenhouse gas contributing to climate change. In this work, we investigate the changes in the global methane budget using a global chemistry‐climate model constrained with methane and its ...

Diagenetic and Hydrothermal Processes Produce Heavy Molybdenum Isotope Signatures in Pelagic Sediments of the North and South Pacific

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Molybdenum isotopes (δ98Mo) have been used for more than two decades to investigate past‐ocean redox conditions due to the distinct behavior of this element in oxic and anoxic environments. The oxic sink is generally accepted to have a near‐constant δ98Mo value of −0.7‰, a value derived primarily from the δ98Mo signatures of Fe–Mn crusts and ...

Testing Volcano Deformation Models Against 3D Seismic Reflection Imagery of Ancient Intrusions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Magma intrusion often drives uplift of the overburden and free surface. Analytical modeling of such surface uplift at active volcanoes allows us to estimate intrusion geometries and positions, as well as volume and pressure changes; these insights have proven critical to forecasting volcanic unrest and eruptions. However, it is rarely possible

Interplay Between Tectonics and Submarine Mass Transport Deposits in Cortes Basin: New High‐Resolution Geophysics in the Outer California Borderland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Outer California Borderland (OCB) is an active transform plate boundary offshore Southern California, where the relationship between faulting and submarine mass transport deposits (MTDs) remains poorly understood. Onshore paleoseismic data provide high‐resolution earthquake records, whereas marine geophysical data capture longer‐term ...
