SAN FRANCISCO — Some 35 years ago, a crew from the PBS science show "Nova" joined a team of scientists from the U.S. Geological Survey as the researchers worked to piece together one of the earliest systemic views of the San Francisco Bay. They explored its physics and its biology, and along the way analyzed a daily flood of discharged sewage, high concentrations of heavy metals, and the demise of shellfish, birds, and other native Bay species.
