Jay Barlow received a B.S. in Biology from Arizona State University and a Ph.D. in Biological Oceanography from Scripps Institution of Oceanography, UCSD. He has been a researcher at the NOAA Southwest Fisheries Science Center in La Jolla California since 1982. His research has primarily involved evaluating and mitigating human impacts on cetaceans and pinnipeds along the US West Coast and in Hawaii. International work has involved surveys of cetacean abundance in the Colombian Amazon, the Yangtze River and the northern Gulf of California. Today we talk about vaquitas, the smallest and most endangered of the cetaceans.
