NoMelt Study Challenges Views of Mantle Dynamics
A study recently published in Nature uses OBS data from the 2011-2013 NoMelt experiment in the Pacific to show that large-scale plate motion may not be the greatest driver of deformation in the oceanic mantle. Click for more information about the NoMelt experiment. (Photo: Jim Gaherty)

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.

Highlights

2016 International Town Hall
The International OBS Town Hall at the 2016 American Geophysical Union Fall Meeting hosted 16 speakers representing 7 different countries. Titles, speakers, and presentations are now available on the OBSIP website.
2015 OBS Symposium
The Ocean Bottom Seismology Symposium in Vancouver, WA, was attended by over 100 participants and featured 18 talks covering a wide range of research topics. Specifications for future OBS instrumentation were also discussed.
OBSIPtec Mailing List
