Bronk, Deborah A.
Assistant Professor - Marine Sciences
Ph.D., 1992, Marine Estuarine and Environmental Sciences, University of Maryland

GARLMER / NSF Research Focus:

To contrast the dissolved organic nitrogen pool in the Georgia Rivers with the pool in Chesapeake Bay. To determine the importance of organic nitrogen as a source of nitrogen to primary and secondary producers in the Georgia Rivers and Chesapeake Bay.

GARLMER / SEA GRANT Research Focus:

To determine the relative contribution of inorganic and organic nitrogen to primary and secondary production in the Georgia Rivers and the near coastal zone.
