Description:
Carry out an exploratory study of bottom sediment erodibility in the muddy northern half of Chesapeake Bay. Compare and evaluate two state-of-the-art techniques for measuring erodibility to ensure high data quality and to investigate potential differences in results. Analyze the data in the context of a newly developed erosion formulation that allows application of results for numerical sediment transport modeling and accounts for a potentially limited supply of erodible sediment. Relate seasonal and spatial changes in erodibility to environmental factors such as grain size distribution, sediment water content, recent sedimentation rate, biological activity, and water quality.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
