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

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 ...
Dissolved organic matter and bacterial production and respiration in the sea-surface microlayer of the open Atlantic and the western Mediterranean Sea
Dissolved organic matter bacterial production respiration the sea-surface microlayer Atlantic the western Mediterranean Sea
<
2014/4/21
The sea-surface microlayer (SML) is the boundary layer between the ocean and the atmosphere. We measured bacterial production and respiration along with dissolved organic carbon (DOC), nitrogen (DON),...
