Dramatic Decline in Organic Carbon Burial in Big Estuary Driven by Dam Construction: Insights From the Yellow River Estuary

open access: yesEarth's Future, Volume 14, Issue 3, March 2026.
Abstract Estuaries and associated shelf deposits, which bury 70%–90% of global marine organic carbon, making them key sites for marine carbon burial. Variations in total organic carbon (TOC) content and the organic carbon burial rate (OCBR) in these sediments strongly influence carbon sequestration dynamics.

A Revised Estimate of Calcium Carbonate Dissolution in Coastal and Shelf Sediments Suggests Large Shelf Exports in the Marine CaCO3 Cycle

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Calcium carbonate (CaCO3) dissolution plays a key role in the marine carbon and alkalinity cycles and the regulation of atmospheric CO2 levels across geological time scales. Until now, most attention has focused on dissolution in the deep sea, while dissolution in coastal and shelf environments remains poorly constrained.

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...

Geochemical Analysis of Diachronous V‐Shaped Ridges and Troughs That Flank the Reykjanes Ridge South of Iceland

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.
