Description:
The basic objective of our proposed work is to quantify the effectiveness of deoxygenation in removing ballast water organisms while reducing ballast tank corrosion and to provide the information required to evaluate the feasibility of Venturi Oxygen Stripping as a cost-effective ballast water treatment. Specifically we proposed to:
- Quantify levels of mortality for planktonic organisms found in Chesapeake Bay (zooplankton, phytoplankton, and microbes) after treatment with the Venturi Oxygen Stripping system a function of time after exposure to hypoxia.
- Quantify corrosion rate of carbon steel under deoxygenated conditions and establish corrosion mechanism.

Featured Fellow
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.
