Innovation: Non-OBSIP Seismic Instrumentation Projects

In addition to supporting conventional passive- and active-source OBS experiments for OBSIP amounting to 919 deployments and recoveries, the WHOI OBS group has undertaken innovative work to advance a wide range other areas of seafloor seismic study and instrumentation.

Pilot project

1998: Ocean Seismic Network Pilot Experiment

An experiment to from late January to early June of 1998 to designed to learn how to make sustained, high-quality, broadband seismic measurements in the deep oceans. MORE (pdf)

AcousticMoored

2004-2005: Acoustically-Linked Moored Buoy Observatory

A buoy-based ocean observatory using acoustic communication to retrieve data from sensors in the water column and on the seafloor out to ranges of three kilometers from the buoy. MORE (pdf)

Lighthouse

2006-2007: Lighthouse® Realtime Seafloor Seismic Station

The WHOI OBS Lab was contracted by Lighthouse, Inc., to design, build, and help deploy two real-time seismic stations in the Gulf of Oman connected by an 80 km fiber-optic cable. MORE (pdf)

Keck1

2008-2009: Keck Combined Strong-Motion/Broadband OBS

W.M. Keck Foundation-funded effort to determine the physical mechanisms responsible for the observed capability to predict, using foreshocks, large (Mw ~6) transform-fault earthquakes at the East Pacific Rise, and to gain greater insight into the fundamentals of earthquake mechanics in general. MORE (pdf)

obs and remus

2015-: Seismic Data Retrieval Using an Autonomous Underwater Vehicle and High-Speed Optical Telemetry

Combining recent advances in optical telemetry and marine robotics, coupled with the availability of COTS low-power seismic sensors, data loggers and atomic clocks to enable multi-year deployments of OBS arrays that capable of delivering high-frequency, accurately-timed seismic data to shore with data latencies of hours to days without OBS recovery. MORE (pdf)
