Abstract. The Catskill Mountains of southeastern New York receive relatively high rates of atmospheric N deposition, and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] concentrations in some streams have increased dramatically since the late 1960s. We measured the chemistry of 39 first- and second-order streams with forested watersheds to determine the variability of nitrogen concentrations within the Catskill Mountain area. We found that some streams have low [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII concentrations throughout the year, some have seasonal cycles of varying amplitude, and some have relatively high concentrations year round. If the concentration ...
