Recalcitrant Dissolved Organic Carbon Fractions

Annual Review of Marine Science, 2013
Marine 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 and chromophoric dissolved organic matter properties of rivers in the USA

Journal of Geophysical Research, 2012
Dissolved organic carbon (DOC) concentration and chromophoric dissolved organic matter (CDOM) parameters were measured over a range of discharge in 30 U.S. rivers, covering a diverse assortment of fluvial ecosystems in terms of watershed size and landscape drained.

Dissolved organic carbon in the ocean

Marine Chemistry, 1990
Abstract 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.

Dissolved Oxygen as an Indicator of Bioavailable Dissolved Organic Carbon in Groundwater

Groundwater, 2011
Concentrations of dissolved oxygen (DO) plotted vs. dissolved organic carbon (DOC) in groundwater samples taken from a coastal plain aquifer of South Carolina (SC) showed a statistically significant hyperbolic relationship. In contrast, DO‐DOC plots of groundwater samples taken from the eastern San Joaquin Valley of California (CA)

Chromophoric dissolved organic matter and dissolved organic carbon in Chesapeake Bay

Marine Chemistry, 2002
Chromophoric 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.

Marine anoxia impede the transformation of dissolved organic carbon released by kelp into refractory dissolved organic carbon

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.

Dissolved organic carbon on Georges Bank

Continental Shelf Research, 1996
Dissolved 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 ...
