Effect of tidal resuspension on benthic–pelagic coupling in an experimental ecosystem study
To test the effect of sediment resuspension on the nutrient and ecosystem dynamics we performed a 4 wk experiment in three 1000 l shear-turbulence-resuspension-mesocosm (STURM) resuspension (R) tanks and three 1000 l ...
Effects of shear stress and hard clams on seston, microphytobenthos, and nitrogen dynamics in mesocosms with tidal resuspension
To test the interacting effects of hard clams Mercenaria mercenaria and bottom shear stress on nutrient- and ecosystem dynamics, we performed a 4 wk experiment in six 1000 l shear turbulence resuspension mesocosms (STURM). ...
The impact of resuspension on sediment mercury dynamics, and methylmercury production and fate: A mesocosm study
The objective of this study was to investigate the effects of resuspension on the fate and bioaccumulation of mercury (THg) and methylmercury (MeHg) in shallow estuarine environments, using mesocosms. Two 4-week experiments ...
Effect of Sediment Manipulation on the Biogeochemistry of Experimental Sediment Systems
(Alliance Communications Group, 2006)
Before biological or biogeochemical experimentation, sediments are often manipulated and defaunated with the use of many different approaches and only modest consideration of treatment effects on sediment biogeochemistry ...
Biofiltration, water quality, and sediment processes
Gypsum dissolution is not a universal integrator of ‘water motion’
(American Society of Limnology and Oceanography, Inc., 2000)
The dissolution of gypsum or plaster of Paris has been widely used as an inexpensive integral measure of ‘water motion’ in the field and in laboratory tanks for studies of physical–biological interactions. Commonly, ...
The effect of resuspension on the fate of total mercury and methyl mercury in a shallow estuarine ecosystem: a mesocosm study
Sediments are the major repository of mercury in estuaries and could be a significant source of Hg to the overlying water column via release from the solid phase during resuspension. There is, however, little information ...
Polychlorinated Biphenyl Release from Resuspended Hudson River Sediment
(American Chemical Society, 2007)
Three shear turbulence resuspension mesocosms (STORM tanks) were used to examine the release of polychlorinated biphenyls (PCBs) from resuspended Hudson River sediment. Twenty-two percent of the resuspended PCBs desorbed ...
