Swath Mapping on the Continental Shelf and Slope: The Eel River Basin, Northern California
Continental Shelf and Slope Eel River Basin
2015/8/13
The STRATAFORM program sponsored by the Office of Naval Research (Nittrouer and Kravitz, 1996, this issue) seeks to understand how sedimentary processes lead to the formation of the stratigraphic sequ...
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
(POM), and nutrients from the Wailuku River, Hawai‘i, U.S.A., were examined under base- and s...
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...
Autochthonous and allochthonous contributions to mesozooplankton diet in a tidal river and estuary: Integrating carbon isotope and fatty acid constraints
Autochthonous allochthonous contributions
2014/4/17
We examined the carbon sources used by bacteria and mesozooplankton in the Scheldt River and estuary
(Belgium, The Netherlands) using a combined stable isotope and fatty acid composition approach. Wa...
Evidence for the role of methane-derived carbon in a free-flowing, lowland river food web
a free-flowing methane-derived carbon
2014/4/17
We measured the d13
C values of dominant primary consumers and their potential food sources in a
groundwater-fed lowland river. The d13
C of most consumers, such as Gammarus and Simulium, reflected...
Short-lived radionuclides (7 Be and 210 Pb) as tracers of particle dynamics in a river system in southeast Michigan
Short-lived radionuclides particle dynamics
2014/4/21
Riverine water samples (dissolved and particulate), surficial bottom sediments, and trapped sediments were
collected mostly monthly from three stations along the Clinton River, in southeastern Michig...
Potamoplankton size structure and taxonomic composition: Influence of river size and nutrient concentrations
Potamoplankton size taxonomic composition
2014/4/30
We measured the size structure and taxonomic composition of phytoplankton in temperate rivers during base
flows of summer to investigate the influence of river size, ambient nutrient conc...
Assessing sources and ages of organic matter supporting river and estuarine bacterial production: A multiple-isotope (D14 C, d 13 C, and d 15 N) approach
Assessing sources organic matter supporting
2014/5/19
We used radiocarbon (D14
C) and stable isotopic (d
13
C, d

N) signatures of bacterial nucleic acids to estimate the
sources and ages of organic matter (OM) assimilated by bacteria in the Huds...
Phytoplankton production in a large, regulated river: A modeling and mass balance assessment
regulated rive Phytoplankton production
2014/5/21
Phytoplankton production in riverine systems is regulated by hydrologic processes and coupled optical dynamics,
which determine the light dosages experienced by phytoplankton during transit within a ...
Transport of dissolved inorganic carbon from a tidal freshwater marsh to the York River estuary
dissolved inorganic carbon freshwater marsh
2014/5/20
The cycling of dissolved inorganic carbon (DIC) and the role of tidal marshes in estuarine DIC dynamics were
studied in a Virginia tidal freshwater marsh and adjacent estuary. DIC was measured over d...
