Brief Bio

Sean Bailey is an oceanographer in the Global Change Data Center at NASA Goddard Space Flight Center (GSFC) and serves as the Manager for the Ocean Biology Distributed Active Archive Center (OB.DAAC). He received a dual-major Bachelors of Science in Marine Science and Biology from the University of Miami in 1992, and a Masters of Science in Biological Oceanography from the University of Southern Mississippi in 1997. His research interests are focused on bio-optical remote sensing of the oceans. In 1997, he was employed by Futuretech Corporation under contract to support the Ocean Biology Processing Group (OBPG) in the Ocean Ecology Branch at NASA Goddard Space Flight Center. In 2015, he left Futuretech to become a civil servant. His duties as the DAAC manager include the management and distribution of the data products produced by the OBPG, the in situ archive component (SeaBASS), and the OBPG science software support team, including the staff responsible for the development and maintenance of the SeaWiFS Data Analysis System (SeaDAS). His work with the OBPG has been focused on the on-orbit calibration of these satellites and the validation of their data products. He has worked on the development and evaluation of algorithms implemented for ocean color satellite data processing, ranging from the atmospheric correction to the bio-optical models that derive geophysical products.
