Margin Seismology
Monterey Bay Ocean Bottom International Science Experiment (MOISE)

MOISE is a multi-faceted undertaking designed to:

  1. Develop and demonstrate ROV installation of a major instrument as part of a Seafloor Observatory project. Although this instrument will only be deployed for three months, most of the manipulations are identical to those required for a permanent deployment.
  2. Collect and evaluate data from a broadband seismometer deployed on the Pacific plate (western side of the San Andreas system of transform faults) to complement data from the land-based seismographs. Anticipated results are better located local events because the site is on the west side of the major structures.
  3. Evaluate the merit of sensor burial and contemporaneous collection of tidal data to offset low-frequency marine noise that has historically obscured data from these types of instruments.
  4. Extract both local and global seismic events to assess the value of a permanent seismic observatory in this type of tectonic setting.
  5. Correlate the non-earthquake events on the broadband instrument, a 1 hz seismometer, a single channel hydrophone and a standard 4.5 hz seismometer to determine whether these represent mass-wasting events.
