Description
| - Mean annual concentrations of SO42- and NO3- in wet-only deposition have decreased between 1988 and 2006 at BBWM due to decreased emissions of SO2 and NOx. Base cations, NH4+ and Cl- concentrations mostly exhibited no trends or statistically significant trends but with change of < 1 ueq L-1 per year from 1988 to 2006. Seasonally, two chemically distinct periods of precipitation (April to September) and (October to March) indicate two different trajectories of air mass movement: dominantly continental sources in the warm season with increased SO42- and NH4+ and mixed continental and marine sources in the cool season with increased inputs of marine aerosols. The major factors driving seasonality of the streams are hydrology, vegetation activity, and temperature. The low flow periods June - October were typical with greater contribution of the deeper flow solutions and increased pH value, anion neutralizing capacity, Si concentration, non-marine Na and low Ali concentrations.
