Ralph F. Keeling is a professor at Scripps Institution of Oceanography. He is the Principal Investigator for the Atmospheric Oxygen Research Group at Scripps and is the director of the Scripps CO2 Program, the measurement program behind the Keeling curve started by his father Charles David Keeling in 1958. He received a B.S. in physics from Yale University in 1979 and a Ph.D. in applied physics from Harvard University in 1988 for developing the first technique to accurately measure atmospheric oxygen. His research interests include climate change, measurements of variations in atmospheric composition, the global carbon cycle, ocean biogeochemistry, and paleoclimate.
Keeling received the Rosenstiel Award in 1992, was an H. Burr Steinbach Visiting Scholar at Woods Hole Oceanographic Institution in 1998, and received the Humboldt Research Award in 2009 in recognition of his career achievements.
