Reappraisal of Holocene Caldera Resurgence at Campi Flegrei (Southern Italy): A Long‐Lived Magma‐Driven Resurgent Dome System

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Seasonal and Interannual Variability of Antarctic Bottom Water Downstream of the Four Key Formation Regions

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic Bottom Water (AABW) is a cold, dense water mass formed around Antarctica that ventilates the global abyssal ocean. Recent studies have reported widespread warming, freshening, and thinning of AABW, yet its temporal variability remains poorly constrained because of sparse observations.

Multi‐Model Ensemble and Reservoir Computing for River Discharge Prediction in Ungauged Basins

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Despite the necessity for accurate flood prediction, many regions lack sufficient river discharge observations. Although numerous models for daily river discharge prediction exist, achieving high accuracy, interpretability, and efficiency under data‐scarce conditions remains a major challenge.

Assessment of a Finite Volume Discretization of the Horizontal Pressure Gradient Force Beneath Sloping Ice Shelves

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract The accurate computation of pressure gradients in ocean models is essential for simulating ocean and climate processes. Inaccurate computation can result in spurious velocities on the order of real ocean flows, particularly in quiescent ice shelf cavities.

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.
