Description:
This proposal continues and expands a project begun in 2000 involving the testing of a variety of technologies for ballast water treatment aboard a vessel in Baltimore Harbor owned by the U S. Maritime Administration. The focus of the current proposal is on combination technologies, specifically UV irradiation and biocide dosing (in series) of ballast water during a ballasting operation, primary filtration (using a depth filter & separator) used in tandem with UV irradiation and primary filtration, UV irradiation and biocide dosing used together.

Featured Fellow
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.
