Review of NOAA’s Plan for the Scientific Data Stewardship Program
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 Change and has taught at the Indian Institute of Technology in Bombay. She is a fellow of the Aldo Leopold Leadership Program.
William J. Emery is a professor at the Colorado Center for Astrodynamics Research in the Department of Aerospace Engineering at the University of Colorado. He received his Ph.D. from the University of Hawaii. His research interests are in satellite remote sensing of the ocean and land surface vegetation. Ocean applications include skin sea surface temperature, the computation of surface currents from satellite images, mapping of geostrophic currents from satellite altimetry, and general air-sea interaction studies. The goal of Dr. Emery’s research is to make satellite data a source of quantitative information that can be incorporated into numerical models of the phenomena controlling these systems. Dr. Emery has served on many panels looking into the creation of long-term climate records from satellite data.
Milton Halem holds an emeritus position as distinguished information scientist with the Earth Science Directorate at the NASA Goddard Space Flight Center (GSFC). Dr. Halem formerly served as assistant director for information sciences and as chief information officer for the GSFC. Dr. Halem has also served as chief of the Earth and Space Data Computing Division, where he was responsible for the development and management of the NASA Center for Computational Sciences, one of the world’s most powerful complexes for scientific data-intensive supercomputing and massive data storage. He acquired his Ph.D. in mathematics from the Courant Institute of Mathematical Sciences at New York University in 1968. He joined NASA in 1971 as the Global Atmospheric Research Program project scientist and later headed up the Goddard Global Modeling and Simulation Branch. His personal achievements include more than 100 scientific publications in the areas of atmospheric and oceanographic sciences and computational and information sciences.
