Organic Carbon Burial Rates in Muddy Temperate Shelf Sea Sediments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Muddy continental shelf sediments act as important sinks for atmospheric CO2 by accumulating organic matter, a small fraction of which is buried and stored as organic carbon (OC) over long timescales. Quantifying long‐term OC burial in shelf sediments is critical for understanding their role in climate regulation; however, this remains ...

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

Source Prediction and Distribution of Organic Matter Across a Land to Ocean Sediment Transect: An Integrative Biogeochemical and Multivariate Machine Learning Approach

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Identifying organic matter (OM) distribution and origins in sediments is vital for distinguishing archival records, depositional dynamics, and extent of terrigenous inputs to marine systems. However, degradation and modification of OM before deposition can camouflage and mask its source signals in sedimentary sinks.

Polar Front System Variability and Its Control on Export Rain Ratio Over the Past 800 ka: Implication for Atmospheric pCO2 Changes

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract Little is known about long‐term variability in the organic carbon to carbonate carbon export rain ratio, despite its key role in the global carbon cycle. Here, we reconstruct glacial‐interglacial changes in the sedimentary rain ratio over the Southern Ocean, using micropaleontological (coccoliths and foraminifera) and geochemical (CaCO3, Total

Impact of an Earthquake Event on Submarine Groundwater Discharge in Jeju Island, Korea

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract This study investigated the impact of a 4.9 magnitude earthquake on submarine groundwater discharge (SGD) and nutrient fluxes along the coast of Jeju Island, Korea. Significant negative correlations were found between salinity and dissolved inorganic nitrogen (DIN; r2 = 0.94), dissolved inorganic phosphorus (DIP; r2 = 0.53), and dissolved ...

Geochemical Evidence for Retention of Particulate Carbon and Mercury Across the Romaine Land‐Ocean Aquatic Continuum

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The land‐to‐ocean aquatic continuum (LOAC) carries contaminants, nutrients, and particulate carbon (C) from inland aquatic systems to the sea, which can impact regional biogeochemical budgets and local ecosystem health. Climate change and other anthropogenic influences (e.g., hydroelectricity) will affect the LOAC across varied watersheds ...
