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

Accumulation of prokaryotic remains during organic matter diagenesis in surface sediments off Peru
Accumulation of prokaryotic organic matter diagenesis
2014/4/18
Bacterial biomarkers (D-amino acids and muramic acid) were investigated in surface sediments (0–1 cm) at 22
stations in the Peru margin. Concentrations were used to quantitatively estimate the relati...
Organic matter diagenesis and bacterial contributions to detrital carbon and nitrogen in the Amazon River system
Organic matter diagenesis bacterial contributions
2014/4/18
Amino sugars and amino acids, including the bacterial biomarkers muramic acid and D-amino acids, were
measured to investigate the diagenetic alterations of and microbial contributions to detrital org...
Across margin export of organic matter by cascading events traced by stable isotopes, northwestern Mediterranean Sea
organic matter stable isotopes northwestern Mediterranean Sea
2014/4/17
We present a 1-yr (2005–2006) record of organic carbon (OC) and total nitrogen (TN) contents and their
isotopic ratios (d13
COC and d15N) in sinking particles from the western Gulf of Lions. Maximum...
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 ...

C-acetate) carbon associated with
benthic organic matter (BOM) was measured at timed intervals to determine the relative...
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...
