EW9510 Seismic Reflection/Refraction

Seismic:Navigation:ShotTime

Seismic Shot Point Navigation Data from the Woodlark Basin acquired during R/V Maurice Ewing expedition EW9510 (1995)

This data set was acquired with the LDEO Multi-Channel Seismic system during R/V Maurice Ewing expedition EW9510 conducted in 1995 (Chief Scientist: Dr. Brian Taylor; Investigators: Dr. Brian Taylor and Dr. Richard Hey). These data files are of ASCII format and include Seismic Shot Point Navigation data that provide the primary seismic navigation source for this cruise. Data were acquired as part of the project: Propagating Rifts and Spreading Centers into Continents: The Woodlark Basin, and funding was provided by NSF grants: OCE92-01691 and OCE95-03505. These data are cited by Taylor et al., 2009.
