Three‐dimensional seismic structure of the Dragon Flag oceanic core complex at the ultraslow spreading Southwest Indian Ridge (49°39′E)

Geochemistry, Geophysics, Geosystems, 2013
The Southwest Indian Ridge (SWIR) is an ultraslow spreading end‐member of mid‐ocean ridge system. We use air gun shooting data recorded by ocean bottom seismometers (OBS) and multibeam bathymetry to obtain a detailed three‐dimensional (3‐D) P wave ...
