William Wilcock is a marine geophysicist who uses earthquake recordings, seismic imaging and modeling techniques to study seafloor volcanoes and hydrothermal systems. He is involved with efforts to deploy seismic and geodetic instruments on the seafloor along the Cascadia subduction zone to understand the region’s seismic hazards. In addition to his work in geophysics, William also studies baleen whales using opportunistic recordings of their subsonic calls by ocean bottom seismometers.
