Carbon source and weather in coastal North Carolina

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The increasing frequency of extreme weather events, including tropical cyclones, is altering the delivery and quality of organic matter (OM) exported from landscapes to estuaries. However, the mechanisms regulating these shifts, especially during multi‐year climatic oscillations, remain poorly understood.

Influence of environmental factors on spectral characteristics of chromophoric dissolved organic matter (CDOM) in Inner Mongolia Plateau, China [PDF]

Hydrology and Earth System Sciences, 2016
Spectral characteristics of chromophoric dissolved organic matter (CDOM) were examined in conjunction with environmental factors in the waters of rivers and terminal lakes within the Hulun Buir plateau, northeast China.

Dissolved organic matter in the northwestern Pacific marginal seas: Insight into the distribution of its optical properties

Frontiers in Marine Science, 2023
Dissolved organic carbon (DOC) and the optical properties of dissolved organic matter (chromophoric- and fluorescent dissolved organic matter; CDOM and FDOM) were measured to determine the distributions and drivers of DOM in the northwestern Pacific ...

Great Slave Lake as a Key Modulator of Dissolved Organic Carbon Fluxes From Boreal Landscapes to the Mackenzie River

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Understanding dissolved organic carbon (DOC) fluxes in boreal freshwater systems is critical for constraining high‐latitude carbon budgets and anticipating climate‐driven changes. Here, we present a retrospective assessment (2000–2024) of DOC fluxes in the Upper Mackenzie River watershed, focusing on Great Slave Lake (GSL), a key hydrological ...

The spectral characterization on chromophoric dissolved organic matter released from leaching of wetland plant litter in Poyang Lake under inundation

All Earth
Chromophoric dissolved organic matter (CDOM) leached from litter plays a key role in wetland biogeochemical cycling. However, the release patterns and driving mechanisms of CDOM from large lake wetland plant litter under inundation remain poorly ...

Satellite observation of Chromophoric Dissolved Organic Matter (CDOM) variability in the wake of hurricanes and typhoons

Geophysical Research Letters, 2002
Satellite observation of Chromophoric Dissolved Organic Matter (CDOM) absorption coefficient variability in the wake of numerous hurricanes and typhoons is reported here for the first time. Storm‐induced vertically‐mixed CDOM from deeper depths has a higher absorption coefficient than the photochemically degraded CDOM within the undisturbed pre‐storm ...

Genomic Survey of Carbon Monoxide Dehydrogenases Reveals Their Widespread Distribution in Marine Habitats

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Protein sequence surveys show that nickel‐ and molybdenum/copper‐containing carbon monoxide dehydrogenases (CODHs) are widespread in the ocean. Phylogenetic and genome context analyses reveal that marine CODHs are highly diverse in both evolutionary history and functional organisation.

Remote Sensing Estimation of CDOM for Songhua River of China: Distributions and Implications

Remote Sensing
Rivers are crucial pathways for transporting organic carbon from land to ocean, playing a vital role in the global carbon cycle. Dissolved organic carbon (DOC) and chromophoric dissolved organic matter (CDOM) are major components of dissolved organic ...

Revisiting the disappearance of terrestrial dissolved organic matter in the ocean: a δ¹³C study [PDF]

Biogeosciences, 2014
Organic carbon (OC) depleted in 13C is a widely used tracer for terrestrial organic matter (OM) in aquatic systems. Photochemical reactions can, however, change δ13C of dissolved organic carbon (DOC) when chromophoric, aromatic-rich terrestrial OC is ...

Distribution and source‐sink dynamics of H2 in the Western Tropical Pacific and their response to La Niña–induced upwelling

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Hydrogen (H2) influences the climate by prolonging the lifetime of greenhouse gases via consuming hydroxyl radicals. Despite the ocean's crucial role in regulating atmospheric H2, its marine biogeochemical cycle is poorly constrained. To bridge this gap, our research in the Western Tropical Pacific Ocean (WTPO) revealed a north–south ...
