Flow and storage in groundwater systems
William Alley, Richard W. Healy, James W. LaBaugh, Thomas E. Reilly
2002, Science (296) 1985-1990
The dynamic nature of groundwater is not readily apparent, except where discharge is focused at springs or where recharge enters sinkholes. Yet groundwater flow and storage are continually changing in response to human and climatic stresses. Wise development of groundwater resources requires a more complete understanding...
Comparison of δ18O measurements in nitrate by different combustion techniques
Kinga M. Revesz, John Karl Bohlke
2002, Analytical Chemistry (74) 5410-5413
Three different KNO3 salts with δ18O values ranging from about −31 to +54‰ relative to VSMOW were used to compare three off-line, sealed glass tube combustion methods (widely used for isotope studies) with a more recently developed on-line carbon combustion technique. All methods yielded roughly similar...

2002, Eos, Transactions, American Geophysical Union (83) 273-278
Recent studies of sedimentology hydrology, and geomorphology indicate that releases from Glen Canyon Dam are continuing to erode sandbars and beaches in the Colorado River in Grand Canyon National Park, despite attempts to restore these resources. The current strategy for dam operations is based on the hypothesis that sand supplied...

Determination of isoxaflutole (balance) and its metabolites in water using solid phase extraction followed by high-performance liquid chromatography with ultraviolet or mass spectrometry
Chung-Ho Lin, Robert N. Lerch, E. Michael Thurman, Harold E. Garrett, Milon F. George
2002, Journal of Agricultural and Food Chemistry (50) 5816-5824
Balance (isoxaflutole, IXF) belongs to a new family of herbicides referred to as isoxazoles. IXF has a very short soil half-life (<24 h), degrading to a biologically active diketonitrile (DKN) metabolite that is more polar and considerably more stable. Further degradation of the DKN metabolite produces a nonbiologically active benzoic...
Effects of stress from mine drainage on diversity, biomass, and function of primary producers in mountain streams
Dev K. Niyogi, William M. Lewis Jr., Diane M. McKnight
2002, Ecosystems (5) 554-567
This paper proposes a hypothesis that relates biodi- versity, community biomass, and ecosystem func- tion to a gradient of stress. According to this hy- pothesis, biodiversity has a low threshold of response to stress, whereas biomass and function are stable or increase under low to moderate stress and decrease...
