Technical Note: Comparison of storage strategies of sea surface microlayer samples [PDF]

, 2013
The sea surface microlayer (SML) is an important biogeochemical system whose physico-chemical analysis often necessitates some degree of sample storage.

The optical characteristics and sources of chromophoric dissolved organic matter (CDOM) in seasonal snow of northwestern China [PDF]

The Cryosphere, 2018
Abstract. Chromophoric dissolved organic matter (CDOM) plays an important role in the global carbon cycle and energy budget but is rarely studied in seasonal snow. A field campaign was conducted across northwestern China from January to February 2012, and surface snow samples were collected at 39 sites in Xinjiang and Qinghai provinces.

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

Frontiers 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 ...

CDOM spectral slope (S275–295) as tracers of water masses, CDOM heterogeneity, and Δ14C‐DOC in an oligotrophic marginal sea

Limnology and Oceanography Letters, 2023
The absorption spectral slope, S275–295, is an optical metric frequently employed for characterizing chromophoric dissolved organic matter (CDOM). We collected CDOM absorption (aCDOM) and fluorescence spectra from the oligotrophic offshore South China ...

Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter [PDF]

, 2017
Sulfate reduction plays an important role in altering dissolved organic matter (DOM) in estuarine and coastal sediments, although its role in the production of optically active chromophoric DOM (CDOM) and a subset of fluorescent DOM (FDOM) has not been ...

The biogeochemistry of carbon across a gradient of streams and rivers within the Congo Basin [PDF]

, 2014
Dissolved organic carbon (DOC) and inorganic carbon (DIC and pCO2), lignin biomarkers and the optical properties of dissolved organic matter (DOM) were measured in a gradient of streams and rivers within the Congo Basin (Republic of Congo), with the aim ...

Diel Bacterioplankton Community Dynamics Under Contrasting Light Regimes. [PDF]

Environ Microbiol Rep
We assessed the diel variability of bacterioplankton communities and influencing parameters in a boreal peat bog and an oligotrophic lake under two different light regimes: more than 20‐h light prevalence in the summer and equal day and night lengths in autumn. Using amplicon sequencing of 16S rRNA transcripts, combined with biogeochemical measurements,

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

E3S 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.

Environmental Calibration of Coral Luminescence as a Proxy for Terrigenous Dissolved Organic Carbon Concentration in Tropical Coastal Oceans

Geochemistry, Geophysics, Geosystems, 2022
The riverine flux of terrigenous dissolved organic matter (tDOM) to the ocean is a significant contributor to the global carbon cycle. In response to anthropogenic drivers the flux is expected to increase.
