Detailed Description

George beside a “birdsfoot tripod” at the Oyster Point Marina in South San Francisco, 1999. The tripod was designed to measure waves, currents, temperature, conductivity (salinity), and suspended-sediment concentration in shallow water in San Francisco Bay. The footpads are foldable to allow deployment from a small boat.
