Dissolved Organic Carbon Fluxes under Bare Soil
Journal of Environmental Quality, 2007ABSTRACTThe flux of dissolved organic carbon (DOC) in soil facilitates transport of nutrients and contaminants in soil. There is little information on DOC fluxes and the relationship between DOC concentration and water flux in agricultural soils. The DOC fluxes and concentrations were measured during 2.5 yr using 30 automatic equilibrium tension plate ...

Chromophoric dissolved organic matter and dissolved organic carbon in Chesapeake Bay
Marine Chemistry, 2002Chromophoric dissolved organic matter (CDOM) is the light absorbing fraction of dissolved organic carbon (DOC). The optical properties of CDOM potentially permit remote sensing of DOC and CDOM, and correction for CDOM absorption is essential for remote sensing of chlorophyll a (chl a) in coastal and estuarine waters.

Dissolved Organic Carbon Retention in Soils
Soil Science Society of America Journal, 2002Interactions between dissolved organic C (DOC) and mineral soils were examined in a laboratory column study. Specific emphasis was given to comparisons of soil and solution measurements of organic C (OC) retention in four soil parent materials. Soil columns were leached with one of three concentrations of forest floor (FF) leachate or distilled water ...

Recalcitrant Dissolved Organic Carbon Fractions
Annual Review of Marine Science, 2013Marine dissolved organic carbon (DOC) exhibits a spectrum of reactivity, from very fast turnover of the most bioavailable forms in the surface ocean to long-lived materials circulating within the ocean abyss. These disparate reactivities group DOC by fractions with distinctive functions in the cycling of carbon, ranging from support of the microbial ...

Dissolved organic carbon on Georges Bank
Continental Shelf Research, 1996Dissolved organic carbon (DOC) in sea water from Georges Bank was measured by a high temperature combustion/direct injection (HTC/DI) technique during the spring bloom period in April 1993. Concentrations in surface waters (72–85 μM) and deep waters (54–56 μM) were similar to DOC concentrations measured in the oligotrophic north-west Atlantic Ocean by ...

Dissolved organic carbon in the ocean
Marine Chemistry, 1990Abstract Soviet investigations of dissolved organic carbon (DOC) in the Peruvian upwelling area, the Bay of Bengal, the Philippine Sea and the Antarctic area are summarized, together with the methodology and a comparison with results of Sugimura and Suzuki (Mar. Chem., 24: 105–131) for the Philippine Sea.

Marine Pollution Bulletin
The transformation of dissolved organic carbon (DOC) released by macroalgae into refractory dissolved organic carbon (RDOC) through microbial carbon pump (MCP) represents a crucial carbon sequestration process. This process mainly takes place in coastal areas, where it is likely affected by marine anoxia.

Classification of Dissolved Organic Carbon
1985This chapter discusses the classification scheme used in this book to describe the nature of dissolved organic carbon. The classification is based on adsorption and ion-exchange chromatography and definitions of classes of organic compounds that constitute dissolved organic carbon.

Snowball Earth prevention by dissolved organic carbon remineralization
Nature, 2007The 'snowball Earth' hypothesis posits the occurrence of a sequence of glaciations in the Earth's history sufficiently deep that photosynthetic activity was essentially arrested. Because the time interval during which these events are believed to have occurred immediately preceded the Cambrian explosion of life, the issue as to whether such snowball ...
