Dissolved Organic Matter (DOM) Dynamics at the Sediment‐Water Interface in the North Sea: Implications for Global Benthic DOM Fluxes

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Sediment–water exchange of dissolved organic matter (DOM) represents a critical yet poorly constrained component of the marine carbon cycle. Here, we combine quantitative, molecular, and carbon isotope (δ13C and F14C) analyses to investigate the production, composition, and export of porewater DOM in the German Bight, North Sea, and evaluate ...

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Cajon Pass and the Southern San Andreas Fault System: Earthquake Cycle Stress Accumulation and Present‐Day Loading

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract With over a century since the last major rupture affecting the wider Los Angeles region, tectonic stress has steadily built along the southern San Andreas and San Jacinto fault systems, raising concerns of an imminent large earthquake. Cajon Pass, located at the junction of these faults, represents a critical site for potential through‐going ...

Deglacial Permafrost Organic Carbon Delivery at the Northern Svalbard Continental Margin: Insights From Tetraether Lipids and Plant Biomarkers

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Degradation of Arctic permafrost due to global warming and sea level rise could trigger positive feedbacks, exacerbating climate change. However, uncertainties remain on how permafrost systems may respond because we lack a complete understanding of the permafrost‐climate feedback.

Subsoil Carbon and δ13C Spatial Patterns Reveal Land Use Legacy in a Sandy Subtropical Ecotone in Brazil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Soil organic carbon (SOC) storage represents one of the most critical ecosystem services provided by soils, yet scientific assessments frequently focus on surface layers, overlooking deeper horizons. In this study, we investigated SOC stocks and spatial patterns of soil δ13C across three contrasting land use and land cover (LULC) types in ...
