Abstract:
Seismic data was acquired to study the transition from rifted continental crust to oceanic crust at the Deep Galicia Margin from June to August 2013. 3D Multichannel reflection and coincident wide-angle seismic data were acquired simultaneously as part of a seismic experiment over an area of 80 km long and 25 km wide in the Deep Galicia margin. The multichannel reflection seismic volume was acquired by the R/V Marcus G. Langseth, which provided a source for the ocean bottom seismic data. A total of 86 ocean bottom hydrophones/seismometer deployments were carried out by F/S Poseidon. Two airgun arrays with total gun volumes of 3,300 cu.in. were deployed as seismic sources. Shots were fired alternately using two source arrays every 37.5 m (shot interval of ~ 16 s with ship speed of 4.5 knots). Data were converted into SEGY format.
