The Marine Nitrogen and Carbon Biogeochemistry group is a research lab started by Dr. Margaret Mulholland in 2001 as part of the Ocean & Earth Sciences (OES) department at Old Dominion University. We study nitrogen and carbon cycling in estuarine, coastal and oligotrophic marine environments. Our research interests include nitrogen and carbon cycling, harmful algal blooms, organic matter cycling, marine nitrogen fixation and bacterial and algal productivity and interactions. The Mulholland Lab also manages the Phytoplankton Analysis Laboratory at Old Dominion University.
