Temporal and spatial variability in the cycling of nitrogen within a constructed wetland: A whole-system stable-isotope-addition experiment
Temporal spatial variability in the cycling of nitrogen a constructed wetland A whole-system stable-isotope-addition experiment
2014/4/17
Constructed wetlands attenuate effluent nutrients, are hydrodynamically well defined, and are a useful proxy for the study of nitrogen (N) transformation in eutrophic natural systems. A whole-system s...
The optical volume scattering function: Temporal and vertical variability in the water column off the New Jersey coast
scattering function Temporal
2014/5/13
I present optical data collected offshore of the New Jersey coast at the Long Term Ecological Observatory LEO-
15 during the summer of 2001. The data were collected by using a LISST-100 instrument, w...
Flow history explains temporal and spatial variation of carbon fractionation in stream periphyton
temporal and spatial variation carbon fractionation stream periphyton
2014/5/9
We investigated factors that contribute to isotopic carbon fractionation in periphytic biofilms in a human-altered headwater stream with a flashy hydrograph. Water velocity had an important effect on ...
Modeling circulation in lakes: Spatial and temporal variations
Modeling circulation in lakes Spatio temporal variations
2014/5/20
The influence of spatial and temporal variations in wind forcing on the circulation in lakes is investigated using field data and the three-dimensional Estuary and Lake Computer Model (ELCOM) applied ...
Methane bubbles in Lake Kinneret: Quantification and temporal and spatial heterogeneity
Methane bubbles Lake Kinneret Quantification temporal and spatial heterogeneity
2014/5/20
The amount of methane bubbles rising from the bottom of Lake Kinneret was quantified by using a dual-beam echo sounder. Both echo-counting (EC) and echo integration (EI) techniques were implemented. B...
Spatio-temporal geochemistry of mercury in waters of the Tapajo′s and Amazon rivers, Brazil
he Tapajo′s Amazon rivers
2014/6/9
Spatial and temporal variations of mercury (Hg) concentrations were monitored in the surface waters from the
lower portion of the Tapajo′s River, the Arapiuns River, its principal tributary, and the ...
