The influence of organic matter dynamics on the cycling of toxic organic contaminants in Chesapeake Bay

Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
- Ecosystems and Restoration
Description:
To relate the cycling of organic pollutants in Chesapeake Bay to seasonal changes in organic matter cycling and sediment transport. We will link compound-specific settling velocities, burial rates, resuspension fluxes, and benthic recycling rates to contaminant sorption and particle characteristics.

Nina Santos
Nina Santos is a Ph.D. student at the Chesapeake Biological Laboratory at the University of Maryland Center for Environmental Science. For her dissertation, she is focused on small shrimp-like crustaceans called mysids – an understudied yet important part of many estuarine and coastal food webs.
Featured Research Project
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.
