Description:
We aim to convert an existing autonomous instrument for phosphate monitoring into an instrument for urea monitoring and integrate the effort with ongoing research to understand, detect and mitigate HABs in Maryland. This will require equipping the existing instrument with a colorimeter/heater in the 520-530 nM range with a higher temperature (~85 degrees vs 50 degrees) capability; optimizing existing urea determination and standardization protocols for interfacing with our instrument; testing the instrument in the laboratory; deploying the instrument in the field; posting the urea data on web sites; and describing our results to colleagues, environmental managers, and the public.

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.
