Experiment Summary

(Taken from NSF Abstract #0327283): An array of twelve ocean-bottom seismometers will be deployed within the 'bull's-eye' region of the Ridge 2000 East Pacific Rise integrated studies site at 9 degrees 50 minutes north. The character of near-axis faulting will be studied, the seismically active hydrothermal system will be mapped, the seismic character of any magmatic activity will be observed, and tidal triggering of seismicity will be studied. The work is coordinated with other multidisciplinary monitoring in the area and the results will be released as rapidly as possible.

Cruises

2003 - 2003

9 SIO short-period OBS were deployed.

2004 - 2004

18 SIO short-period OBS were deployed (105 was not deployed) and 9 SIO short-period OBS were recovered.

2005 - 2005

12 SIO short-period OBS were deployed and 18 SIO short-period OBS were recovered.

3/28/2006 - 4/3/2003

11 SIO short-period OBS were deployed (306 was not deployed) and 4 SIO short-period OBS were recovered with the R/V Knorr [KN182-13]. 5 SIO short-period OBS (201, 202, 203, 208, 211) were unresponsive and 3 were stuck.

1/10/2007 - 2/5/2007

8 SIO short-period OBS were recovered with the R/V Atlantis [AT15-15]. 3 SIO short-period OBS (303, 305, 309) were unresponsive or stuck.
