To continue quantification of the impact of the Baltimore/Washington urban area on atmospheric depositional fluxes to the northern Chesapeake Bay through a consistent long-term sampling program at urban and down-wind sites; To, through the release of purposeful tracers of diesel soot exhaust, track the urban plume and characterize size distributions and deposition of combustion-derived aerosol particles; To determine, through intensive sampling programs under winter and summer conditions, the magnitude and variability of atmospheric and surface water concentrations, and of estimated gas exchange rates, or semivolatile organic contaminants and mercury species.
