Rise of the Machines: Computational Power and the History of NASA’s Ocean Color Missions

Sept. 30, 2015; 3:30 pm (EDT); NASA GSFC, Building 3 Auditorium

The processing of ocean color data from satellite-borne remote sensing instruments such as the Coastal Zone Color Scanner (CZCS) (active 1978-1986), the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) (active 1997-2010), and the Moderate Resolution Imaging Spectroradiometer (MODIS) (active 2000-present) would be difficult, if not impossible, without the parallel rapid growth in computer processing ability.

Join Dr. James Acker, Senior Support Scientist at the Earth Observing System Data and Information System (EOSDIS) Goddard Earth Science Data and Information Services Center (GES DISC), for a discussion of how increasing computational power along with improved data processing speed helped make global mapping of ocean chlorophyll concentrations possible. Dr. Acker also will show how these developments gave the power of data processing and visualization to the user community via SeaWiFS Data Analysis System (SeaDAS), a system that emulated NASA’s Ocean Data Processing System (ODPS), and the Web-based GES-DISC Interactive Online Visualization and Analysis Infrastructure (Giovanni) data visualization interface.

Dr. Acker earned his Ph.D. in chemical oceanography from the University of South Florida, and has demonstrated the use of ocean color data and Giovanni through research and peer-reviewed papers on phytoplankton blooms in the Chesapeake Bay, the unique biology of the northern Red Sea, and the export of calcium carbonate sediments from the Bahamas, Bermuda, and coral atolls caused by tropical storm systems. His recent book, “The Color of the Atmosphere with the Ocean Below: A History of NASA’s Ocean Color Missions,” was funded jointly by the NASA Science and History divisions.

This year marks the 50th anniversary of the Scientific Colloquia Series. Colloquia are held Wednesdays in the Building 3 Auditorium at NASA’s GSFC in Greenbelt, MD, and are free of charge. For more information, including a schedule of the Fall-Winter 2015-2016 Colloquia Series, please visit http://scicolloq.gsfc.nasa.gov/.

Please note that access to NASA’s Goddard Space Flight Center is limited to those holding NASA badges or official visitors. If you would like to attend this presentation and are a U.S. citizen but do not possess a NASA badge, please call the Colloquium Committee Chair, Dr. David Thompson, at 301-286-8168.
