Resuspension and transport of sediment-associated toxics in the northern Chesapeake Bay bottom

- Ecosystems and Restoration
Description:
The objectives of the proposed study are: 1) To investigate the resuspension and transport of fine sediments in the northern Chesapeake Bay, characterizing temporal and spatial variability in resuspension processes 2) To investigate the influence resuspension on the time varying flux of toxics across the sediment-water interface, and to examine how resuspension affects partitioning of toxics between continuously suspended particulates, tidally resuspended particulates, bottom sediments, and dissolution; 3) To relate resuspension and transport of sediment associated toxics to more easily measureable or predictable sediment and physical forcing 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.

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.
