  • Special Interest Group at 2014 IRIS Workshop
    April 22, 2014
    The Ocean Bottom Seismograph Instrument Pool will host a Special Interest Group (SIG) Meeting at the 2014 IRIS Workshop. The SIG will focus on soliciting input from the seismology community to identify the key concerns and services that OBSIP should provide in the future. The IRIS workshop will be held from June 8 - June 11, 2014 in Sunriver, Oregon. (more)
  • Cascadia Data Restriction
    February 28, 2014
    The OBSIP Management Office (OMO) has restricted access to the Cascadia Initiative dataset (network ID 7D) at the IRIS Data Management Center (DMC) in order to resolve a channel naming error that results in a large number of stations having an incorrect relative orientation. (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.
