Tidal and subtidal exchange in Delaware's Inland Bays. Nutrient and carbon fluxes from tributary watersheds to Delaware's Inland Bays. Input of groundwater and associated nutrients to Delaware's Inland Bays. Inputs From Surface Waters. Base flow and storm discharge sampling continues.
Analytical work continues.
Initial analysis of the first year data is beginning. Additional studies of the spatial variability of atmospheric N concentrations and fluxes are planned. A particular focus will be on the ammonia gas concentrations, as these may reflect specific agricultural practices in the watershed. Analysis of thermal imagery continues. Seismic and ground-penetrating radar studies will start in the spring of 2000, possibly with the addition of a resistivity survey to map subsurface salinities.
