The effect of macrophytes on nitrogen cycling in sediments                 will be studied.  The research will focus on how two nitrogen                   transformations, nitrification and demitrification, are                         influenced by the release of oxygen from the roots of submerged                 macrophytes, from both freshwater and marine ecosystems.                             Intact vegetated and non-vegetated sediment cores will serve               as the experimental systems.  Nitrogen transformations will be                  measured using 15N techniques. At the same time, oxygen gradients               near the roots and rhizomes will be measured using oxygen                       electrodes.  The results of this study should contribute in                     important ways to our understanding of the role of macrophyte                   beds in nitrogen cycling in aquatic ecosystems.                                      The facilities at the University of Maryland's Horn Point                  Environmental Laboratories are excellent for this type of                       research.  Dr. Kemp is a fine researcher who will be able to                    advise Ms. Caffrey as she works on this project.
