EW0410 Seismic Reflection/Refraction
Seismic:WideAngle:OBS
Ocean bottom seismometer data at the Blanco Transform in the Pacific Ocean, acquired during R/V Maurice Ewing expedition EW0410 (2004)
The Blanco Transform Seismic cruise acquired marine seismic reflection and refraction data at the Blanco Transform in the Pacific Ocean. A companion program, EW0305, took place in 2003 where fast-spreading oceanic crust is exposed at Hess Deep. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286.
