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 ...

Submarine mud volcanoes as a source of chromophoric dissolved organic matter to the deep waters of the Gulf of Cádiz

Scientific Reports, 2021
Seafloor structures related to the emission of different fluids, such as submarine mud volcanoes (MVs), have been recently reported to largely contribute with dissolved organic matter (DOM) into the oceans. Submarine MVs are common structures in the Gulf

Reactivity of chromophoric dissolved organic matter (CDOM) to sulfate radicals: Reaction kinetics and structural transformation

Water Research, 2019
Sulfate radical (SO4•-) has been extensively studied as a promising alternative in advanced oxidation processes (AOPs) for water treatment. However, little is known about its reactivity to the ubiquitous dissolved organic matter (DOM) in water bodies.

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.

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 ...

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 ...

Glacial Meltwater Promotes Biological Productivity and Subsequent Dissolved Organic Carbon Accumulation in the Eastern Ross Sea: Evidence From the Austral Summer of 2023

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract The Ross Sea, a critical region for global carbon cycling, receives increasing glacial meltwater from West Antarctica, yet the impact on regional carbon cycling remains poorly understood. A key uncertainty is how this meltwater influences dissolved organic matter (DOM), particularly in the historically inaccessible eastern Ross Sea. This study

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 ...
