Janet Campbell and her research team are developing techniques for studying biological and biogeochemical processes in the ocean using satellite remote sensors. Their primary sources of data are ocean color satellite sensors such as the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) and the Moderate Resolution Imaging Spectroradiometer (MODIS). They are modeling the effects of phytoplankton, dissolved organic materials, suspended sediments, and other particles on the spectral radiance measured by these satellites, and are exploring inversion techniques for using the satellite ocean color data to map these substances. Techniques are being developed for estimating primary productivity in coastal waters, and for blending regional models for coastal applications. Dr. Campbell is a member of NASA’s SeaWiFS and MODIS science teams. As a member of the MODIS team she is responsible for developing algorithms and strategies for monitoring chlorophyll and primary productivity in coastal ocean, estuarine, and inland waters. Dr. Campbell has been an associate research professor at the University of New Hampshire (UNH) since 1993, and is a member of the Graduate Faculty. Between 1997 and 1999, she served as the NASA program manager for ocean biology and biogeochemistry. Before coming to UNH she was a research scientist at the Bigelow Laboratory for Ocean Sciences in Boothbay Harbor, Maine (1982-1993), where she established and directed the remote-sensing computer facility. She previously worked as an aerospace technologist and engineer at the NASA Langley Research Center in Hampton, Virginia. She holds a Ph.D. in statistics from Virginia Polytechnic Institute.
Ruth DeFries is an associate professor at the University of Maryland, College Park, with joint appointments in the Department of Geography and the Earth System Science Interdisciplinary Center. She investigates the relationships between human activities, the land surface, and the biophysical and biogeochemical processes that regulate Earth’s habitability. She is interested in observing land cover and land use change at regional and global scales with remotely sensed data and exploring the implications for such ecological services as climate regulation, the carbon cycle, and biodiversity. Dr. DeFries obtained a Ph.D. in 1980 from the Department of Geography and Environmental Engineering at Johns Hopkins University and a bachelor’s degree in 1976 from Washington University with a major in Earth science. Dr. DeFries has worked at the National Research Council with the Committee on Global
