RCL Gulf of California receiver function model (2008)

RCL Gulf of California receiver function model (2008)

Large-scale model for the Gulf of California Region based on receiver functions and surface wave inversions. The triangles are the NARS-Baja stations and the green circles are locations of receiver functions. The depth panels in the right panel show the shear-wave velocity along transects denoted by the lines on the map. The southernmost E-W panels shows the sharp athenosphere anomaly associated with the spreading center, while the northernmost panel shows a diffuse athenosphere upwelling.

RCL Gulf of California seismometer locations (2008)

RCL Gulf of California seismometer locations (2008)

Location of the SCOOBA OBS stations (triangles), and complementary on-shore broadband stations (squares). Also shown are CMT mechanisms for two large events recorded by the array, as well as locations for over 30 local events (black circles). NARS-Baja = Margins-funded temporary deployment. RESBAN = regional network operated by CICESE. Image from the MARGINS 2008 Decadal Review research nugget.

OBS recovery at EPR with Jason 2 (2007)

Video thumbnail for OBS recovery at EPR with Jason 2 (2006)

The Jason 2 Remote Operated Vehicle (ROV) frees an ocean bottom seismometer and sends it to the surface after it had become stuck in lava during a seafloor eruption at the East Pacific Rise study site during late 2005 - early 2006.
