OBSIP Experiment Archive

The below information pertains to experiments that happened under The Ocean Bottom Seismograph Instrument Center (OBSIP) (prior to Feb 2019) only.  These records contain schedules, project summaries, links to data sets along with a visual map for all experiments.  For information on current experiments or experiments under OBSIC (2019-current), please view the OBSIC Experiment List.


The Ocean Bottom Seismograph Instrument Pool - “OBSIP” was established in 1999 as a National Science Foundation (NSF) instrument facility that provides ocean bottom seismometers to support research and further our understanding of marine geology, seismology and geodynamics.

OBSIP was funded by the NSF and was comprised of a Management Office (IRIS) and three Institutional Instrument Contributors - Lamont Doherty Earth Observatory (LDEO), Scripps Institution of Oceanography (SIO), and Woods Hole Oceanographic Institution (WHOI), each of whom contributed both instruments and technical support to the pool.

Ocean bottom seismometers available through OBSIP, included both broadband instruments for long-term deployment of passive experiments, and short period instruments that are used for active seismic refraction studies in coordination with vessels towing airgun arrays.  OBSIP worked closely with the University National Oceanographic Laboratory System (UNOLS) in scheduling cruises to support OBSIP experiments.
