Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach. [PDF]

Environ Microbiol Rep
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Temperature Thresholds Govern Microbial-Mediated Dissolved Organic Carbon Dynamics in Coastal Ecosystems. [PDF]

Adv Sci (Weinh)
Coastal dissolved organic carbon (DOC) represents one of the largest reduced carbon pools on Earth, and they are influenced by temperature. Across 7.6–35.9 °C ranges, the microbial‐mediated DOC dynamics is characterized by three temperature thresholds.

Factors regulating the compositions and distributions of dissolved organic matter in the estuaries of Jiaozhou Bay in North China

Oceanologia, 2020
Summary: Water samples collected from the Jiaozhou Bay every two months between April 2016 and February 2017 were analyzed for dissolved organic carbon (DOC), particulate organic carbon (POC), total dissolved carbohydrates (TCHO), total hydrolyzed amino ...

Characteristics, sources and driving factors of riverine CDOM in a severe erosion basin on the Loess Plateau, China

Ecological Indicators, 2023
Chromophoric dissolved organic matter (CDOM) plays a crucial role in aquatic ecosystems and biogeochemical processes. The characteristics, sources and influencing factors of riverine CDOM were determined with 56 samples collected in the Wuding River (WDR)

Seasonal Dynamic of CDOM in a Shelf Site of the South-Eastern Ligurian Sea (Western Mediterranean)

Journal of Marine Science and Engineering, 2020
Chromophoric dissolved organic matter (CDOM) is the fraction of the Dissolved Organic Carbon (DOC) mainly absorbing UV and blue radiation, influencing water optical properties, light availability for primary production, and water-leaving radiance.

Grazing impact on chromophoric dissolved organic matter (CDOM) by the larvacean Oikopleura dioica [PDF]

Marine Ecology Progress Series, 2006
Experiments were conducted to determine if the pelagic larvacean Oikopleura dioica could graze on chromophoric dissolved organic material (CDOM) and if so, could such grazing affect the optical characteristics of the water column. Although O. dioica was found to graze on CDOM, it also contributes to the CDOM pool. O. dioica cleared large, >10 kDa CDOM,

CDOM Spatiotemporal Variability in the Mediterranean Sea: A Modelling Study

Journal of Marine Science and Engineering, 2021
This study investigates the spatial and temporal variability of chromophoric-dissolved organic matter (CDOM) in the Mediterranean Sea. The analysis is carried out using a state-of-the-art 3D biogeochemical model. The model describes the plankton dynamics,

Parameterization of the light absorption properties of chromophoric dissolved organic matter in the Baltic Sea and Pomeranian lakes [PDF]

Ocean Science, 2016
This study presents three alternative models for estimating the absorption properties of chromophoric dissolved organic matter aCDOM(λ). For this analysis we used a database containing 556 absorption spectra measured in 2006–2009 in different regions of ...

Optical characteristics and factors that influence representative Lakes in the Taihu Lake basin, China

Journal of Freshwater Ecology, 2022
From 2018 to 2019, a survey of a typical lakes system in the Taihu Lake basin, China, was carried out. To provide reference values for the restoration and management of submerged vegetation in the lakes, the optical attenuation coefficient (Kd) and ...
