Iron Isotope Evidence for Heightened Primary Productivity Triggered by Hydrothermally Sourced Nutrients During Oceanic Anoxic Event 2

open access: yesGeophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Oceanic Anoxic Event 2 (OAE2, ∼94 Ma) represents a major global cycle perturbation in the mid‐Cretaceous greenhouse that is commonly attributed to increased biological primary productivity stimulated by elevated nutrients. However, whether increased nutrients were sourced from submarine volcanism or enhanced continental weathering remains ...

Evidence for Petit‐Spot Volcanism in the Puerto Rico Trench

open access: yesGeophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Petit‐spot volcanism occurs in intraplate settings along the outer rise of subducting plates. Here we present evidence for petit‐spot type of volcanism from multibeam bathymetry and backscatter data from the Puerto Rico Trench (PRT). It is the first report of such volcanism in the Atlantic basin. Up to 34 possible petit‐spot volcanic cones are

Neon Isotopes in Geothermal Gases From the Kenya Rift Reveal a Common Deep Mantle Source Beneath East Africa

open access: yesGeophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract The seismic velocity structure beneath East Africa suggests interconnected corridors of hot mantle are upwelling beneath the continent. However, the geochemical evidence for deep mantle in Ethiopia‐Kenya‐Tanzania volcanism is sparse questioning the existence of superplume.
