Intro
I began working for the U.S. Geological Survey in 1997. One of my primary research interests is long-term monitoring and trend analyses. This research involves collecting and analyzing long-term monitoring data to determine the effects of climate and land use change on water quality, water quantity and soil chemistry in minimally disturbed watersheds across the United States. I also conduct watershed research in the Catskill Mountains of New York which is the primary source of drinking water for New York City. My work in the Catskills during the last 2 decades has included the effects of agricultural best management practices on stream water quality, nutrient cycling, and sediment transport. Recently I have become involved in evaluating the effectiveness of green infrastructure in Buffalo, NY as part of the Great Lakes Restoration Initiative.

Recent climate trends and implications for water resources in the Catskill Mountain region, New York, USA
Climate scientists have concluded that the earth’s surface air temperature warmed by 0.6 °C during the 20th century, and that warming induced by increasing concentrations of greenhouse gases is likely to continue in the 21st century, accompanied by changes in the hydrologic cycle. Climate change has important implications in the Catskill region of southeastern New York State, because the region is

Factors controlling soil water and stream water aluminum concentrations after a clearcut in a forested watershed with calcium-poor soils
The 24 ha Dry Creek watershed in the Catskill Mountains of southeastern New York State USA was clearcut during the winter of 1996-1997. The interactions among acidity, nitrate (NO3- ), aluminum (Al), and calcium (Ca2+) in streamwater, soil water, and groundwater were evaluated to determine how they affected the speciation, solubility, and concentrations of Al after the harvest. Watershed soils wer

The impact of runoff generation mechanisms on the location of critical source areas
Identifying phosphorus (P) source areas and transport pathways is a key step in decreasing P loading to natural water systems. This study compared the effects of two modeled runoff generation processes - saturation excess and infiltration excess - on total phosphorus (TP) and soluble reactive phosphorus (SRP) concentrations in 10 catchment streams of a Catskill mountain watershed in southeastern N

Stream-water chemistry, nutrients, and pesticides in Town Brook, a headwater stream of the Cannonsville Reservoir Watershed, Delaware County, New York, 1999
Stream-water chemistry was monitored from January 1 through December 31, 1999, in the Town Brook watershed (TBW) in Delaware County, N.Y. to provide a basis for future evaluation of the effectiveness of Best Management Practices (BMPs) in decreasing agricultural nutrient and pesticide leaching to receiving waters. Total runoff from the watershed during 1999 was 664 millimeters (mm). Annual nutrien
