Dr. Enfield graduated in Physics and Geophysics from the University of California (Berkeley) in 1965. Following a stint in the Peace Corps teaching undergraduate Physics at a Chilean university (1965-1967), he obtained M.S. and Ph.D. degrees in Physical Oceanography at Oregon State University (OSU) in 1970 and 1973. He worked two years each as UNESCO Expert in Physical Oceanography in Ecuador (1973-1975) and as Scientific Liaison for the IDOE Coastal Upwelling Ecosystems Analysis (CUEA) Program in Peru (1975-1977). From 1977 through 1987 he did research and graduate teaching at Oregon State University, eventually becoming Associate Professor on the OSU academic faculty. Since 1987 he has been a research oceanographer at the NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Florida.
