Fluorescence spectroscopy applied to the optimisation of a desalting step by electrodialysis for the characterisation of marine organic matter [PDF]

, 2009
The isolation and characterisation of marine dissolved organic matter (DOM) are still not readily achieved today. The study of this chemically complex material is particularly difficult, especially as it is hindered by the high salinity of seawater.

Seasonal dynamics of dissolved organic matter in a small tropical estuary-coastal bay continuum: distribution, transformation, flux, and global perspectives

Frontiers in Marine Science
The export and transformation of riverine dissolved organic matter (DOM) at the river-sea interface are critical to understanding carbon budgets in tropical regions, yet remain underexplored in small watersheds.

Spectrophotometric studies of marine surfactants in the southern Baltic Sea

Oceanologia, 2015
It is well known that surfactants in the southern Baltic Sea constitute the organic matter from riverine waters discharges as well as the secondary degradation products of marine phytoplankton excretion.

Fragmentation‐Locked Polymeric Carbon Nitride Enables Global‐to‐Local Electron Allocation for Enhanced Peroxymonosulfate Activation

Small, EarlyView.
A NaI‐assisted polymeric carbon nitride photocatalyst enables visible‐light‐driven peroxymonosulfate activation through fragmentation‐locked structural and electronic regulation. Iodide‐induced ultrathin nanosheets expose abundant active sites, while sodium ions promote global‐to‐local electron allocation toward peroxymonosulfate.

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

Machine Learning Algorithms for Chromophoric Dissolved Organic Matter (CDOM) Estimation Based on Landsat 8 Images

Remote Sensing, 2021
Chromophoric dissolved organic matter (CDOM) is crucial in the biogeochemical cycle and carbon cycle of aquatic environments. However, in inland waters, remotely sensed estimates of CDOM remain challenging due to the low optical signal of CDOM and ...

Tropical Sources Dominate the Ocean Carbonyl Sulfide Budget

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Carbonyl sulfide (OCS) regulates stratospheric aerosol–climate interactions and helps to track terrestrial photosynthesis. Using OCS to infer drivers of stratospheric aerosol loading or biospheric productivity requires understanding its largest and most uncertain natural source—ocean emissions. Top‐down ocean OCS budget estimates inferred from

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 ...

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...
