Fluoreszierendes gelöstes organisches Material (FDOM) in Küstenmeeren: Charakterisierung, biogeochemische Prozesse, und die Möglichkeit der in situ Überwachung
Das gelöste organische Material (DOM) der Meere ist eine wichtige Komponente globaler Stoffkreisläufe. In dieser Arbeit wurde zum ersten Mal DOM in einem unterirdischen Ästuar (STE) mit optischen und molekularen Methoden untersucht. Vergleichend wurde zudem ein klassisches Ästuar untersucht, beide …

Marsh-Exported Dissolved Organic Matter Fate in Estuaries
… fluorescent dissolved organic matter (CDOM and FDOM) from various sources within the Rhode River, a brackish, eutrophic, sub-estuary during the summer, and seasonally across four Chesapeake Bay marshes, were examined. Microbial (14 d in the dark) and photochemical incubations (7 d in light …

Microbial Degradability of Terrigenous, Marsh-Exported, and Estuarine Colored Dissolved Organic Matter in Long Island Sound
… and spectral slopes) and spectrofluorometry (FDOM excitation-emission matrices). Dissolved organic carbon (DOC), mass spectrometry (FT-ICR-MS), and microbial count samples were also taken at each measurement point.</p> <p>Our results emphasize the impact of terrigenous and anthropogenic DOM on …

Physical and Biological Drivers of Wetlandscape Biogeochemistry
… fluorescent dissolved organic matter sensors (fDOM) and applied river solute transport frameworks and metrics to wetland catchments. I found that there was heterogeneity in wetland response to changing hydrology and that seasonality and potentially bathymetry influences fDOM concentrations. …

Bioavailability of dissolved organic matter in coastal waters
… and reemits the energy again (Fluorescence, FDOM). The relation between the optical properties of DOM and the bioavailability of DOC was tested in the Ría de Vigo. This study demonstrated that it was possible to derive both the bioavailable DOC and its rate constants from the DOM protein-like …

Temporal variability of fluorescent dissolved organic matter at a brackish, tidal marsh-estuary interface
<p>Marshes are both terrestrial and aqueous, sitting as an intermediate between land and water. Studies over constrained numbers of tidal cycles have demonstrated that these marshes are net exporters of dissolved organic carbon (DOC) to adjoining estuaries, however, there is need for continuous …

Dinámica de gases invernadero en un sistema estuarino
… La mayor parte de la fracción fluorescente (FDOM) es de origen alóctono, predominando los componentes húmicos (84 ± 14 %) sobre los proteicos (14 ± 6 %). Los componentes húmicos se correlacionan con la salinidad, mientras que los proteicos están más relacionados con la producción autóctona y …
