ATMOSPHERIC DISPERSION OVER CHESAPEAKE BAY

Estimating effective longitudinal dispersion in the Chesapeake Bay

An analysis of Environmental Protection Agency’s Chesapeake Bay Program hydrographic dataset shows that the bay responds coherently to variability in freshwater flux. Mean salinity and salinity stratification both respond to variability in freshwater flux on time scales of roughly 90 days. Stratification is also influenced by local wind forcing but on much shorter (4e5 day) time scales. The vol...

Interactive Chesapeake Bay Simulation

Scientists use sophisticated numerical models to study ocean circulation and other physical systems, but the complex nature of such simulation software generally make them inaccessible to non-expert users. In principle, however, numerical models represent an ideal teaching tool, allowing users to model the response of a complex system to changing conditions. We have designed an interactive simu...

GIS/EM4 - Modeling Atmospheric Nitrogen Deposition and Transport in the Chesapeake Bay Watershed: A GIS Approach

Abstract The atmospheric deposition of nitrate and ammonia species has been identified as a major factor in the decline of water quality in the Chesapeake Bay. Recent reports have indicated that atmospheric deposition may account for 25 to 80% of the total nitrogen load entering the Bay. However, many uncertainties exist regarding the accuracy of these estimates including the accuracy of the at...
