Episodes of low dissolved oxygen indicated by ostracodes and sediment geochemistry at Crystal Lake, Illinois, USA
low dissolved oxygen stracodes sediment geochemistry
2014/4/17
Low dissolved oxygen during the summer and early fall controls profundal continental ostracode distribution
in Crystal Lake (McHenry County), Illinois, favoring Cypria ophthalmica and Physocypria glo...
Decadal diagenetic effects on d13 C and d15N studied in varved lake sediment
Decadal diagenetic effects varved lake sediment
2014/4/18
To assess the long-term (27 yr) effects of sediment aging on stable carbon and nitrogen isotope values (d13
C
and d15N), we used a collection of eight freeze cores of annually laminated (varved) lak...
Ecological, landscape, and climatic regulation of sediment geochemistry in North American sockeye salmon nursery lakes: Insights for paleoecological salmon investigations
sediment geochemistry Ecological landscape climatic
2014/4/17
We used multiple linear regressions across a Northeast Pacific region 56-lake set to examine the influence of
sockeye salmon spawner densities and limnological, climatic, and watershed characteristic...
Glider observations of sediment resuspension in a Middle Atlantic Bight fall transition storm
sediment resuspension a Middle Atlantic Bight fall transition storm
2014/4/18
In October of 2003 a fleet of autonomous underwater gliders began a time series of transects across the New
Jersey shelf. The gliders are equipped with a conductivity–temperature–depth sensor, and so...
Nitrogen incorporation and retention by bacteria, algae, and fauna in a subtropical intertidal sediment: An in situ 15N-labeling study
Nitrogen incorporation retention by bacteria
2014/4/22
We performed a 15N-labeling study to investigate nitrogen incorporation and retention by the benthic
microbial community (bacteria and benthic microalgae) and fauna in the intertidal sediment of the ...
Long-term changes in the areal hypolimnetic oxygen deficit (AHOD) of Onondaga Lake: Evidence of sediment feedback
Long-term changes areal hypolimnetic oxygen
2014/4/30
Long-term trends in the rate of depletion of hypolimnetic dissolved oxygen (DO) are documented for ionically
enriched hypereutrophic Onondaga Lake, New York, for the 1978–2002 interval. Depletion rat...
Coupling of near-bottom seston and surface sediment composition: Changes with nutrient enrichment and implications for estuarine food supply and biogeochemical processing
near-bottom seston surface sediment composition Changes with nutrient enrichment estuarine food supply biogeochemical processing
2014/5/8
We compared near-bottom seston and surface sediment composition in Cape Cod estuaries receiving different N loads to determine whether eutrophic-driven changes in seston and sediment composition occur...
Sediment–water exchange of total mercury and monomethyl mercury in the San Francisco Bay–Delta
Sediment–water exchange monomethyl mercury
2014/5/19
Five field trips were conducted in the San Francisco Bay–Delta between May 2000 and October 2001 to investigate the sediment–water exchange of total mercury (Hg) and monomethyl mercury (MMHg). S...
Distribution of viruses and bacteria in relation to diagenetic activity in an estuarine sediment
viruses bacteria sediment
2014/5/21
The distribution of viruses and bacteria was investigated in relation to bacterial sulfate reduction and total respiration (production of dissolved inorganic carbon, [DIC]) in a coastal sediment. Vira...
