Due to their proximity to the New York-New Jersey metropolitan region, the Catskills receive high rates of atmospheric nitrogen deposition. Our research is focused on identifying the major controls on nitrate export from these forested watersheds. The Catskill watersheds provide 90% of the drinking water for New York City residents, making the results of our research relevant to land managers as well as ecologists.
Air pollutants are deposited not only in rain and snow, but also as gases, particles, and fog droplets. Measuring the deposition of all of these forms is difficult, especially in mountainous terrain, where deposition rates are strongly influenced by elevation and characteristics of the forest canopy. Knowing the rates and patterns of deposition is critical to evaluating ecosystem response to the pollutants
