Maria Tzortziou

Dr. Tzortziou's research integrates multidisciplinary datasets, satellite observations, and ecosystem models to provide mechanistic insights into the impacts of human and environmental pressures on biogeochemical cycles and ecological processes along the continuum of terrestrial, wetland, estuarine, and open ocean ecosystems. A key objective of her research is applying results to link science to practice and enhance decision support systems. Dr. Tzortziou has led numerous field campaigns across a range of environments, from the tropics to the Arctic, and has received two NASA Group Achievement Awards (2016, 2019) as Science Team member of the DISCOVER-AQ and OWLETS missions.

Dr. Tzortziou is on the Science Steering Committee for the Ocean Carbon Biogeochemistry Program, the Science Leadership Board of the North American Carbon Program, and member of the Arctic Research Consortium of the United States (ARCUS). She is on the Editorial Board of Remote Sensing and Associate Editor for Biogeosciences. Dr. Tzortziou serves as the Deputy Program Applications Lead for PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), a strategic NASA satellite mission that will extend key ocean color, aerosol, and cloud data records for Earth system and climate studies. She is the Applied Science Lead and Science Team member for NASA's recently selected Earth Venture Instrument-5 Investigation GLIMR (Geostationary Littoral Imaging and Monitoring Radiometer), a new instrument competitively selected by NASA to provide unique observations of ocean biology, chemistry, and ecology that are critically needed to improve coastal resource management, enhance decision making, and enable rapid response to natural and man-made coastal hazards.
