Characterization of the key pathways of dissimilatory nitrate reduction and their response to complex organic substrates in hyporheic sediments
Characterization of the key pathways dissimilatory nitrate reduction their response to complex organic substrates hyporheic sediments
2014/4/4
Laboratory incubations with river-bed sediment collected from riffles and pools were used to quantify potential pathways of dissimilatory nitrate reduction in the hyporheic zone of a groundwater-fed r...
Dissolved and particulate organic matter source-age characterization in the upper and lower Chesapeake Bay: A combined isotope and biochemical approach
Dissolved and particulate organic matter source-age characterization the upper and lower Chesapeake Bay A combined isotope and biochemical approach
2014/5/4
In order to characterize the sources and ages of organic matter contributing to river and estuarine outflow waters, the present study investigated Δ14C and δ13C signatures of the major operationally d...
Molecular-level chemical characterization and bioavailability of dissolved organic matter in stream water using electrospray-ionization mass spectrometry
Molecular-level chemical characterization bioavailability dissolved organic matter stream water electrospray-ionization mass spectrometry
2014/5/8
We used electrospray-ionization mass spectrometry (ESI-MS) to characterize, at the compound level, dissolved organic matter (DOM) composition and bioavailability in two streams. There was considerable...
