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...
Basin scale distribution of chromophoric dissolved organic matter in thePacific Ocean
Basin scale distribution chromophoric dissolved organic matter the Pacific Ocean
2014/4/18
Chromophoric dissolved organic matter (CDOM) was surveyed along the 160uW transect from the equatorial to the subarctic Pacific. CDOM characteristics were evaluated through the measurement of fluoresc...
Characteristics and sources of chromophoric dissolved organic matter in lakes of the Yungui Plateau, China, differing in trophic state and altitude
Characteristics sources of chromophoric dissolved
2014/4/17
The high-mountain lakes on the Yungui Plateau in China are exposed to high-intensity ultraviolet radiation, and
contain low concentrations of chromophoric dissolved organic matter (CDOM). We determin...
Effects of fetch and dissolved organic carbon on epilimnion depth and light climate in small forest lakes in southern Sweden
ight climate epilimnion depth
2014/4/16
We sampled small (0.03 to 3.3 km2
surface area) forest lakes in southern Sweden during two summers to
investigate how concentration of dissolved organic carbon (DOC) and lake size influence epilimni...
Contrasting the influences of stream inputs and landscape position on bacterioplankton community structure and dissolved organic matter composition in high-elevation lake chains
Contrasting landscape position
2014/4/18
We examined bacterioplankton community composition (BCC; using polymerase chain reaction-based
phylogenetic fingerprinting) and the composition of dissolved organic matter (DOM; using scanning fluoro...
Increases in the longwave photobleaching of chromophoric dissolved organic matter in coastal waters
longwave photobleaching chromophoric dissolved organic matter
2014/4/17
Salinity effects on the photobleaching of chromophoric dissolved organic matter (CDOM) due to coastal
mixing were investigated through a comparative study of surrogate and surface-water CDOM. Suwanne...
Patterns and regulation of dissolved organic carbon: An analysis of 7,500 widely distributed lakes
Patterns regulation dissolved organic carbon 7,500 widely distributed lakes
2014/4/22
Dissolved organic carbon (DOC) is a key parameter in lakes that can affect numerous features, including microbial metabolism, light climate, acidity, and primary production. In an attempt to understan...
Photochemical production of dissolved organic carbon from resuspended sediments
Photochemical production dissolved organic carbon resuspended sediments
2014/5/5
A series of controlled photolysis experiments using simulated sunlight was conducted in the presence and absence of estuarine bottom sediments to address the role of sediment resuspension on dissolved...
Groundwater-transported dissolved organic nitrogen exports from coastal watersheds
Groundwater-transported dissolved organic nitrogen exports coastal watersheds
2014/5/5
We analyzed groundwater-transported nitrogen (N) exports from 41 watershed segments that comprised 10 Cape Cod, Massachusetts watersheds to test the hypotheses that chemical form of N exports is relat...
Bioreactivity of estuarine dissolved organic matter: A combined geochemical and microbiological approach
