Mangrove peat and algae leachates elicit rapid and contrasting molecular and microbial responses in coastal waters

Communications Earth & Environment, 2023
As sea level rises, previously sequestered blue carbon can be exported offshore as particulate or dissolved organic matter where it may be re-mineralized or sequestered.

Sources, spectral characteristics, and fluxes of dissolved organic matter in coastal groundwater and river water in western Guangdong, China

Frontiers in Environmental Science, 2022
Groundwater discharge and river runoff are two important ways for allochthonous dissolved organic matter (DOM) to enter the ocean, but they vary spatially.

Distribution, spectral characteristics, and seasonal variation of dissolved organic matter in the northern Beibu Gulf, South China Sea

Frontiers in Marine Science, 2022
Dissolved organic matter (DOM) in the land–ocean interface plays a critical role in the global carbon cycle, yet its dynamic is not well understood. Dissolved organic carbon (DOC) in the northern Beibu Gulf was measured seasonally from April 2020 to ...

The importance of the dissolved organic matter pool for the carbon sequestration potential of artificial upwelling

Frontiers in Marine Science, 2022
In the face of climate change there is a need to reduce atmospheric CO2 concentrations. Artificial upwelling of nutrient-rich deep waters has been proposed as a method to enhance the biological carbon pump in oligotrophic oceanic regions in order to ...

Characteristics of Dissolved Organic Matter and Trihalomethane Forming Potential Occurrence in Watersheds with Different Upstream Land Use

Environment and Natural Resources Journal, 2023
Dissolved organic matter (DOM) is the most important natural organic matter (NOM) fraction which reacts with chlorine to form harmful trihalomethanes (THMs) in water bodies. The characteristics of DOM could be affected by land use in the catchment, hence

Estimating submarine groundwater discharge in Jeju volcanic island (Korea) during a typhoon (Kong-rey) using humic-fluorescent dissolved organic matter-Si mass balance

Scientific Reports, 2021
We examined the residence time, seepage rate, and submarine groundwater discharge (SGD)-driven dissolved nutrients and organic matter in Hwasun Bay, Jeju Island, Korea during the occurrence of a typhoon, Kong-rey, using a humic fluorescent dissolved ...

Solid phase extraction of ocean dissolved organic matter with PPL cartridges: efficiency and selectivity

Frontiers in Marine Science, 2023
Our current knowledge of the chemical composition of ocean dissolved organic matter (DOM) is limited, mainly because of its extreme molecular diversity, low concentration of individual compounds and the elevated ionic strength of ocean waters.

Study of the effect of pH, salinity and DOC on fluorescence of synthetic mixtures of freshwater and marine salts [PDF]

, 1999
In order to provide support for the discussion of the fate of organic matter in estuaries, a laboratory simulation was performed by changing freshwater ionic strength, pH and organic matter content. The change in spectroscopic characteristics caused by

Performance of Alum Coagulation and Adsorption on Removing Organic Matter and E. coli [PDF]

Nature Environment and Pollution Technology, 2023
Surface water is the primary resource for raw water in drinking water treatment processes. Therefore, the presence of microorganisms, bacteria, and viruses should be the main focus in drinking water treatment, in addition to natural organic matter, which
