Role of plankton in controlling the partitioning and transport of hydrophobic organic contaminants
Principal Investigator:
Joel E. BakerStart/End Year:
1990 - 1993Institution:
Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
- Ecosystems and Restoration
Description:
In field collections of surficial sediments, sediment traps material and 4 size fractions of suspended particles, the concentration and distribution of hydrophobic organic contaminants (HOC) will be quantified. Parallel laboratory studies will examine the speciation and binding of contaminants to phytoplankton and the role of specific organic pools (lipids and pigments) in HOC movement.

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.
