The Dissolved Organic Carbon Controversy:An Update
Dissolved Organic Carbon Controversy An Update
2015/8/19
This note is intended as an update on activities to improve the measurement of dissolved organic carbon (DOC) in seawater. The exciting and controversial paper by Sugimura and Suzuki (1988) led to ren...
Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes
The ecological system lakes
2014/10/16
Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes。
Regional-scale variation of dissolved organic carbon concentrations in Swedish lakes
Organic carbon lakes
2014/10/16
We assessed spatial variability in dissolved organic carbon (DOC) concentrations measured in nearly 2000
Swedish lakes. Inter-lake variance peaked at two different scales, representing within-region ...
Production of dissolved organic matter by phytoplankton and its uptake by heterotrophic prokaryotes in large tropical lakes
Production of dissolved organic matter by phytoplankton heterotrophic prokaryotes large tropical lakes
2014/7/10
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
New insights on the mineralization of dissolved organic matter in central, intermediate, and deep water masses of the northeast North Atlantic
New insights mineralization dissolved organic matter central, intermediate deep water masses northeast North Atlantic
2014/4/2
An optimum multiparameter (OMP) analysis was applied to samples collected during a cruise in the northeast North Atlantic with the aim of objectively defining water mass realms and calculating water m...
Fluxes of dissolved aluminum and manganese to the Weddell Sea and indications for manganese co-limitation
Fluxes dissolved aluminum manganese to the Weddell Sea indications manganese co-limitation
2014/4/2
The trace metals aluminum (Al) and manganese (Mn) were studied in the Weddell Sea in March 2008.Concentrations of dissolved Al ([Al]) were slightly elevated (0.23–0.35 nmol L21) in the surface layer c...
Removal of dissolved inorganic carbon in the Yellow River Estuary
dissolved inorganic carbon Yellow River Estuary
2014/4/2
The Yellow River of China runs mainly through an arid and semiarid midlatitude region that has experienced
substantial anthropogenic and climatic change. This area includes the carbonate-rich Loess P...
Physical responses of small temperate lakes to variation in dissolved organic carbon concentrations
dissolved organic carbon concentrations lakes
2014/4/2
We used a mechanistic physical model to examine the effect of variability in dissolved organic carbon (DOC)
concentrations on the physical properties of small temperate lakes. The model was validated...
Response of phytoplankton in an alpine lake to inputs of dissolved organic matter through nutrient enrichment and trophic forcing
Response of phytoplankton trophic forcing
2014/4/2
Inputs of terrestrially derived dissolved organic matter (DOM) are increasing in alpine lakes due to multiple
drivers such as climate change, tree line advancement, and insect epidemics. A 21 d micro...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...
The spectral slope coefficient of chromophoric dissolved organic matter (S275–295) as a tracer of terrigenous dissolved organic carbon in river-influenced ocean margins
The spectral slope coefficient chromophoric dissolved organic matter S275–295 tracer of terrigenous dissolved organic carbon river-influenced ocean margins
2014/4/4
The present study demonstrates that the spectral slope coefficient of chromophoric dissolved organic matter (CDOM) between 275 nm and 295 nm (S275–295) can be used as a tracer of the percent terrigeno...
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures of a lake food web
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures a lake food web
2014/4/4
Temporal variation in the baseline stable carbon isotope (δ13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankter Daphnia ...
Floodplain influence on dissolved organic matter composition and export from the Mississippi–Atchafalaya River system to the Gulf of Mexico
Floodplain influence dissolved organic matter composition export from the Mississippi–Atchafalaya River system Gulf of Mexico
2014/4/4
Comparisons of the concentrations and compositions of dissolved organic matter (DOM) between the lower Mississippi River (MR) and its distributary, the Atchafalaya River (AR), indicated a strong influ...
Discharge of dissolved black carbon from a fire-affected intertidal system
Discharge of dissolved black carbon from a fire-affected intertidal system
2014/4/4
We report substantial tidal fluxes of dissolved black carbon (DBC) in a fire-affected marsh in the northern Gulf of Mexico. DBC was molecularly determined as benzenepolycarboxylic acids in a tidal cre...
