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...
Optical characterization of chromophoric dissolved organic matter using wavelength distribution of absorption spectral slopes
Optical characterization chromophoric dissolved organic matter wavelength distribution absorption spectral
2014/4/17
We use a new approach to characterize the absorption characteristics of chromophoric dissolved organic matter (CDOM) in standard solutions and in several tropical lake ecosystems (Lake Victoria, Lake ...
Decomposition of plankton-derived dissolved organic matter in permeable coastal sediments
plankton-derived dissolved organic matter coastal sediments
2014/4/16
We tested the hypothesis that dissolved organic carbon (DOC) is degraded when filtered through permeable
shelf sediments. In a laboratory flume experiment the concave shape of DOC profiles observed i...
Tidal marshes as a source of optically and chemically distinctive colored dissolved organic matter in the Chesapeake Bay
Tidal marshes optically chemically distinctive colored dissolved organic matter the Chesapeake Bay
2014/4/21
The role of tidal marshes as a source of dissolved organic carbon (DOC) and colored dissolved organic matter (CDOM) for adjacent estuarine waters was studied in the Rhode River subestuary of the Chesa...
Absorption spectral slopes and slope ratios as indicators of molecular weight, source, and photobleaching of chromophoric dissolved organic matter
Absorption spectral slopes slope ratios indicators of molecular weight source photo bleaching chromo phoric dissolved organic matter
2014/4/21
A new approach for parameterizing dissolved organic matter (DOM) ultraviolet-visible absorption spectra is presented. Two distinct spectral slope regions (275–295 nm and 350–400 nm) within log-transfo...
Seasonal bioavailability of dissolved organic carbon and nitrogen from pristine and polluted freshwater wetlands
Seasonal bioavailability pristine
2014/5/19
We examined the chemical composition and bioavailability of dissolved organic carbon (DOC) and nitrogen
(DON) from two pristine and two polluted cedar bog wetlands across three seasons. Pristine and ...
Competition between biological and photochemical processes in the mineralization of dissolved organic carbon
Competition biological photochemical processes
2014/5/14
The photo- and bioreactive components of dissolved organic matter (DOM) from three different environments were
determined during long-term decomposition experiments. Terrigenous DOM was collected fro...
