Description:
The primary objectives of this proposal are to apply a new direct measurement technique for denitrification to: examine approaches to determining system-wide denitrification estimates in the Choptank River subestuary and determine if oligohaline marshes are important sites for estuarine denitrification. Denitrification will be compared to N input terms available for this subestuary, as well as N sinks including marsh N storage and burial.

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.
