Description:
The objectives of this research are to reliably measure the direct fluxes of trace elements across the sediment-water interface of field-collected cores, measure temporal and spatial variability of such fluxes and determine the importance of Mn, Fe and S redox cycling on trace element production and consumption. This project will determine whether the recycling of metals within surficial sediments has an important impact on water column metal concentrations.

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.
