BIRPS (British Institutes Reflection Profiling Syndicate) 3DEPR-ARAD seismic data (1997)

The 3D multi channel seismic data were acquired as part of a collaborative investigation into models of magmatic segmentation between the Scripps Institute of Oceanography and BIRPS (the British Institutions Reflection Profiling Syndicate). The 3D EPR (East Pacific Rise) ARAD (Anatomy of a Ridge Axis Discontinuity) EW9707 cruise was undertaken in September and October 1997 to provide both refelction and wide-angle seismic data for the study of the overlapping spreading centre (OSC) at 9 degrees 3 minutes N on the East Pacific Rise. The data were acquired with a single source and a single streamer with a nominal line spacing of 100 m. The 3D-EPR ARAD survey was a joint NERC/NSF (US National Science Foundation) funded project and the copyright for this survey is held jointly. Reference: Bazin, S. Harding, AJ. et al.

该三维多通道地震数据是斯克里普斯海洋研究所与英国反射剖面联合机构（BIRPS）合作研究岩浆分段模型的一部分。1997年9月至10月，开展了东太平洋隆起（EPR）ARAD（隆起轴线不连续性的解剖学）EW9707航次，旨在为东太平洋隆起9度3分N处的重叠扩张中心（OSC）提供反射和宽角地震数据。数据采集采用单一源和单一流式传输，线间距为100米。3D-EPR ARAD调查是NERC/NSF（美国国家科学基金会）联合资助的项目，该调查的版权由双方共同持有。参考文献：Bazin, S.，Harding, AJ. 等。（2001）东太平洋隆起9度3分N处浅层地壳的三维就位，地球物理研究杂志。
