Appendix A (FIG. A1). Stream water nitrate concentrations and mean watershed N deposition rates for each of the four synoptic surveys. Regressions between mean catchment N deposition and stream water NO3- concentrations for each survey [September 2004: NO3 = 0.043 NDep -0.31; April 2005: NO3 = 0.0579 NDep -0.43; May 2007: NO3 = 0.071 NDep -0.46, October 2008: NO3 = 0.042 NDep -0.30]. Mean catchment N deposition rates were calculated from an N deposition map developed for GSMNP (Weathers et al. 2006).
