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。
Fluorescence spectroscopy opens new windows into dissolved organic matter dynamics in freshwater ecosystems: A review
dissolved organic matter dynamics A review
2014/4/17
The biochemical composition of dissolved organic matter (DOM) strongly influences its biogeochemical role in
freshwater ecosystems, yet DOM composition measurements are not routinely incorporated int...
Bioavailability and export of dissolved organic matter from a tropical river during base- and stormflow conditions
Bioavailability base- stormflow conditions
2014/4/18
Concentrations, bioavailability, and export of dissolved organic matter (DOM), particulate organic matter
(POM), and nutrients from the Wailuku River, Hawai‘i, U.S.A., were examined under base- and s...
Microbially induced flocculation of allochthonous dissolved organic carbon in lakes
Microbially induced allochthonous dissolved organic carbon
2014/4/17
The flocculation of allochthonous dissolved organic carbon (DOC) in lakes was investigated in a series of
laboratory experiments. Flocculation was enhanced by increased temperatures, and addition of ...
Assessing the dynamics of dissolved organic matter (DOM) in coastal environments by excitation emission matrix fluorescence and parallel factor analysis (EEM-PARAFAC)
Assessing the dynamics dissolved organic matter
2014/4/21
The distributions of fluorescent components in dissolved organic matter (DOM) from Ise Bay, Japan, were
determined by excitation emission matrix (EEM) fluorescence spectroscopy combined with parallel...
Spatial and temporal variability of solar ultraviolet exposure of coral assemblages in the Florida Keys: Importance of colored dissolved organic matter
Spatial and temporal variability solar ultraviolet exposure
2014/4/21
Solar ultraviolet (UV) radiation can have deleterious effects on coral assemblages in tropical and subtropical
marine environments, but little information is available on UV penetration into ocean wa...
Salt marshes as a source of chromophoric dissolved organic matter (CDOM) to Southern California coastal waters
Salt marshes chromophoric dissolved organic matter
2014/4/21
To determine chromophoric dissolved organic matter (CDOM) sources in Southern California coastal waters,
optical properties of a river outlet and adjacent tidally flushed salt marshes were monitored ...
Determining net dissolved organic carbon production in the hydrographically complex western Arctic Ocean
Determining net dissolved organic hydrographically complex western Arctic Ocean
2014/4/22
Each spring and summer, the Chukchi Sea in the western Arctic Ocean experiences a short but intense
phytoplankton bloom that is controlled by sea ice cover, nutrient availability, and river runoff. D...
Red and black tides: Quantitative analysis of water-leaving radiance and perceived color for phytoplankton, colored dissolved organic matter, and suspended sediments
Red and black tides water-leaving radiance
2014/5/5
Using field measurements and quantitative modeling, we demonstrate that red coloration of the sea surface is
not associated with any particular group of phytoplankton and is strongly dependent on the...
Colored Dissolved Organic Matter in the Coastal Ocean: An Optical Tool for Coastal Zone Environmental Assessment and Management
Deep blue sea sea coastal waters
2015/7/29
The phrase "deep blue sea" is so common in English usage that all three words are individually synonymous for "ocean." Poems, song titles, and movies, have used these words to conjure up images that f...
The stoichiometry of dissolved organic carbon, nitrogen, and phosphorus release by a planktonic grazer, Daphnia
dissolved organic carbon nitrogen phosphorus release
2014/5/19
We examined the relationship between Daphnia release rates and ratios of dissolved organic carbon (DOC),
nitrogen (N), and phosphorus (P) and the elemental composition of algal food. We constructed a...
Degradation of dissolved organic matter in oxic and anoxic lake water
Degradation anoxic lake water
2014/5/14
Decades of conflicting results have fueled a debate about how O2
affects organic matter (OM) degradation and
carbon cycling. In a laboratory study, using both OM taken directly from a humic la...
Metabolic and structural response of hyporheic microbial communities to variations in supply of dissolved organic matter
hyporheic microbial communities Metabolic
2014/5/21
Hyporheic sediment bacterial communities were exposed to dissolved organic matter (DOM) from a variety of
sources to assess the interdependence of bacterial metabolism and community composition. Expe...
Abundance of amino sugars and peptidoglycan in marine particulate and dissolved organic matter
amino sugars peptidoglycan
2014/5/20
Several recent studies indicated that amino sugars were likely to be major components of marine carbon and
nitrogen cycles, but there has been insufficient data to investigate this hypothesis. ...
