J. Weiss, Isabelle M. Cozzarelli
2008, Groundwater (46) 305-322
In order to evaluate natural attenuation in contaminated aquifers, there has been a recent recognition that a multidisciplinary approach, incorporating microbial and molecular methods, is required. Observed decreases in contaminant mass and identified footprints of biogeochemical reactions are often used as evidence of intrinsic bioremediation, but...

I. B. Kuffner, V. J. Paul, R. Ritson-Williams, T. D. Hickey, L. J. Walters
2008, Conference Paper, 11th International Coral Reef Symposium Proceedings
To understand the current community structure on reefs in the Dry Tortugas, we conducted specieslevel surveys of macroalgae, coral diversity, herbivorous and game fishes, urchins, and substratum composition (e.g., rugosity) in shallow (3- to 5-m depth) low-relief reef and hardbottom habitats in October 2007. We had particular interest in the...

Benjamin A. Brooks, James Foster, David Sandwell, Cecily J. Wolfe, Paul G. Okubo, Michael P. Poland, David Myer
2008, Science (321) 1177
We demonstrate that a recent dike intrusion probably triggered a slow fault-slip event (SSE) on Kilauea volcano's mobile south flank. Our analysis combined models of Advanced Land Observing Satellite interferometric dike-intrusion displacement maps with continuous Global Positioning System (GPS) displacement vectors to show that deformation nearly identical to four previous...

Nutrient Concentrations and Their Relations to the Biotic Integrity of Nonwadeable Rivers in Wisconsin
Dale M. Robertson, Brian M. Weigel, David J. Graczyk
2008, Professional Paper 1754
Excessive nutrient [phosphorus (P) and nitrogen (N)] input from point and nonpoint sources is frequently associated with degraded water quality in streams and rivers. Point-source discharges of nutrients are fairly constant and are controlled by the U.S. Environmental Protection Agency's (USEPA) National Pollutant Discharge Elimination System. To reduce inputs from...
