The Monterey Bay Ocean Bottom International Seismic Experiment (MOISE) has successfully deployed a suite of geophysical and oceanographic instrument packages on the ocean floor using the Monterey Bay Aquarium Research Institute's (MBARI) Ventana, a tethered Remotely Operated Vehicle (ROV).The goal of this international cooperative experiment is to advance the global Seafloor Observatory effort by developing a prototype suite of instruments and installing them on the western side of the San Andreas fault system offshore of central California. The centerpiece of the instrument suite was a digital broadband seismometer package partially buried within the sediment-covered floor of Monterey Bay, 40 km offshore and 10 km west of the San Gregorio fault at a depth of 1015 m (Figure 1).
