My interests focus on the biogeochemistry and ecology of coastal regions, particularly those influenced by riverine processes. I'm presently working on two strands of research. The first seeks to characterize distributions of carbon dioxide, air-sea carbon exchange, productivity and acid stress in freshwater-influenced coastal regions. The second strand involves the use of data from a variety of space-borne sensors to characterize net community productivity and carbon exchanges in coastal waters. For these projects we use a variety of remotely sensed data including ocean color, sea surface temperature and microwave radiometry. Our UNH Coastal Carbon Group maintains several autonomous data collecting assets in the Gulf of Maine and stays active in cruise campaigns throughout the western Atlantic. I'm currently the Principal Investigator of the NASA-UNH mission GLIMR, (Geostationary Littoral Imaging and Monitoring Radiometer), a hyper spectral ocean color instrument that is scheduled to be placed in geostationary orbit in 2026.
