Ballast Water Technology Demonstration Program (Shipboard Evaluations of Venturi Oxygen Stripping : Determining Mechanical and Biological Efficacy)
Principal Investigator:
Mario N. TamburriStart/End Year:
2004 - 2007Institution:
Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
- Aquatic Invasive Species
Description:
The full-scale controlled experiments under real-world conditions evaluations of Venturi Oxygen Stripping will be divided into two distinct phases or objectives: 1) Engineering Efficacy: Install and verify operational abilities, effectiveness to produce intended conditions, and reliability of the VOS systems onboard active vessels. 2) Biological Efficacy: Test the ability of VOS to reduce concentrations of living ballast water organisms, during normal vessel operations, to meet draft International Maritime Organization (IMO) standards.

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.
