Chromophoric Dissolved Organic Matter and Dissolved Organic Carbon in Lakes Across an Elevational Gradient From the Mountains to the Sea

open access: yesEarth and Space Science, 2022
Dissolved organic matter (DOM) in lakes across elevation gradients is a complex function of topography, climate, vegetation coverage, land use, and lake properties. To examine sources and processing of DOM from sea level to mountain lakes (3–1,574 m), we

Synchronous Shifts in Nutrients and Organic Carbon Responses Over the Diatom-to-Dinoflagellate Succession

open access: yesFrontiers in Marine Science, 2022
Phytoplankton blooms, including the diatom-to-dinoflagellate succession in coastal regions, are frequently observed by researchers through incubation experiments, albeit mainly in nutrient-enrichment conditions. This study, complementary to such previous

Remote determination of chromophoric dissolved organic matter in lakes, China

open access: yesInternational Journal of Digital Earth, 2013
Chromophoric dissolved organic matter (CDOM) strongly influences the water-leaving radiance from aquatic ecosystems. In most inland waters, the remote determination of CDOM absorption presents a central challenge due to their complex optical conditions.

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

open access: yesJournal 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 ...

UV Absorption Spectral Characteristics of Dissolved Organic Matter in Fen River of Taiyuan in China

open access: yesE3S Web of Conferences, 2018
UV absorption is one of the important properties of chromophoric dissolved organic matter (CDOM). The UV absorption spectral characteristics of dissolved organic matter (DOM) were analyzed to infer the main components in Taiyuan urban section.

A new model for the global biogeochemical cycle of carbonyl sulfide – Part 1: Assessment of direct marine emissions with an oceanic general circulation and biogeochemistry model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
The global budget of tropospheric carbonyl sulfide (OCS) is believed to be at equilibrium because background air concentrations have remained roughly stable over at least the last decade. Since the uptake of OCS by leaves (associated with photosynthesis)

Formation of Chromophoric Dissolved Organic Matter by Bacterial Degradation of Phytoplankton-Derived Aggregates

open access: yesFrontiers in Marine Science, 2018
Organic matter produced and released by phytoplankton during growth is processed by heterotrophic bacterial communities that transform dissolved organic matter into biomass and recycle inorganic nutrients, fueling microbial food web interactions ...

Origin and Dynamics of Dissolved Organic Matter in a Mariculture Area Suffering From Summertime Hypoxia and Acidification

open access: yesFrontiers in Marine Science, 2018
Based on six cruises from March to September in 2016, we investigated monthly distributions of dissolved organic matter (DOM) and ancillary water chemistry parameters in a mariculture area in the Northern Yellow Sea, where summertime hypoxia and seawater

Organic matter in aqueous soil extracts: Prediction of compositional attributes from bulk soil mid-IR spectra using partial least square regressions

open access: yesGeoderma, 2022
Water-extractable organic matter (WEOM) is labile and a key component of soil organic matter. Thus, the prediction of soil WEOM concentration and composition-related characteristics is of great interest.

Hydrography of chromophoric dissolved organic matter in the North Atlantic

open access: yesDeep Sea Research Part I: Oceanographic Research Papers, 2007
The distribution and optical absorption characteristics of chromophoric dissolved organic matter (CDOM) were systematically investigated along three meridional transects in the North Atlantic Ocean and Caribbean Sea conducted as part of the 2003 US CLIVAR/CO2 Repeat Hydrography survey.
