  • Call for Participation in GeoPRISMS ENAM Community Seismic Experiment
    November 25, 2013
    Applications are being solicited to participate in the GeoPRISMS Eastern North America Community Seismic Experiment (ENAM CSE), which will collect a suite of active and passive source seismic data along the mid-Atlantic coast. The ENAM CSE involves offshore and land deployment of seismometers that will record land and marine seismic sources and marine multi-channel seismic data acquisition. (more)
  • 2013 OBS Workshop Highlights
    November 04, 2013
    The 2013 OBS Workshop was held in Redondo Beach, CA on October 22-23. Over 100 participants attended, with a strong contingent of early career scientists and international scientists. There were 19 scientific talks, 7 of which were given by international speakers. Talk topics included both scientific results and engineering and instrumentation developments. There was an additional Cascadia Initiative mini-workshop held prior to the OBS workshop. (more)

Marianas Trench
In early 2012, OBSIP supported an experiment that deployed both broadband and short period ocean-bottom seismometers in an area located along the Mariana Trench in the western Pacific Ocean to image and explore the relationships between serpentinization and seismicity in a subduction zone. The R/V Langseth was employed to shoot airguns over the short period OBS array of the active seismic portion of the experiment.

Chile 2013 Recovered
OBSIP recently recovered 10 broadband ocean bottom seismometers off the coast of Chile. These instruments will be used by Principal Investigator Anne Trehu to study the post-seismic response updip of the February 27, 2010 Chilean megathrust earthquake.

The Cascadia Initiative
OBSIP is staying busy this summer and fall supporting up to seven cruises for the recovery and redeployment of 60 Cascadia OBS instruments. The Cascadia Amphibious Array is part of the larger Cascadia Initiative - a community experiment enabled with American Recovery and Reinvestment Act funds to study the structure of the Cascadia subduction zone.

The Ocean Bottom Seismograph Instrument Pool (OBSIP)

The U.S. National Ocean Bottom Seismograph Instrument Pool provides instrumentation to support research to further our understanding of marine geology, seismology and geodynamics. Funded through the NSF, the Pool makes ocean bottom seismic equipment available to all interested researches, to private and public organizations, and to industry.
