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.
