    Cascadia Data Un-restricted The Cascadia Initiative data (Network ID: 7D) has been corrected and is now un-restricted at the IRIS Data Management Center (DMC) as of 5/2/2014. The data was restricted on 2/28/14 to correct the horizontal channel convention for a subset of the data. The OBSIP Management Office apologizes for the delay in re-releasing the data, we wanted to make sure that all the corrected data was uploaded accurately and that no pieces of data were missing. All researchers using the Cascadia data set should re-download the data. (more)
  • 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)
ENAM 2014 Experiment deployed
In April 2014, 30 long-period WHOI OBS instruments were deployed for the ENAM Community Experiment. The ENAM Community Seismic Experiment will focus on the mid-Atlantic Eastern North American rifted margin. The experiment is designed to acquire data that can be used to address key questions in the GeoPRISMS science plan concerning the formation and post-rift evolution of rifted continental margins at a variety of scales.

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.
