Monterey Ocean Bottom Broadband Project
Data access | Reports | Collaborations
The BSL has collaborated with the Monterey Bay Aquarium Research Institute (MBARI) in two experiments on ocean-bottom instrumentation:
- Monterey Bay Ocean Bottom International Seismic Experiment (MOISE)
- Monterey Ocean Bottom Broadband (MOBB) Project
The MOISE and MOBB deployments are multi-purpose experiments to develop, install, and operate a seafloor observatory. The MOISE experiment was conducted from 6/10/1997 - 9/10/1997 and all equipment was successfully recovered. The MOBB deployment began on 4/12/2002 and is planned as a permanent installation. The MOBB seismometer package and its installation are supported by NSF (EAR-9911392).

As part of this collaboration, the borehole sites will have two sets of digital
data loggers. The table below lists which channels will be recorded and the
SEED network and location codes which will be used.

Waveform data from the ocean-bottom deployments are available in
SEED format at the
Northern California Earthquake Data Center,
but are not currently distributed using the standard
tools such as SeismiQuery and NetDC. The NCEDC is working to
to make these data available in the same way as other BK stations;
for the moment, interested users are encouraged to
request a research account.
