Abstract:
During RV SONNE cruise SO111, five 50 to 60 km long seismic refraction and wide-angle profiles were shot on the eastern flank of the Juan de Fuca Ridge near 48°N, southwest of Vancouver Island, Northeastern Pacific. All profiles were shot in 1996 and run parallel to the strike of the spreading centre and sampled crust created 0.5 Myr to 2.6 Myr ago. In total, 24 ocean-bottom-hydrophones (OBH) were deployed to record shots fired using a single low-frequency airgun source (main source frequency of 4-12 Hz). 23 OBH provided data useful for geophysical data analyses.
