Processed multichannel seismic data in the Salton Trough, acquired in 2011 as part of the Salton Seismic Imaging Project (SSIP)

Part of the Salton Seismic Imaging Project (SSIP), this 2011 survey of the Salton Trough collected 48-channel MCS and OBS data with a deep acquisition system tailored to enhance penetration. A 17 m motor vessel towed a 30 m barge from which the instruments were deployed. SALTON2010 was a companion survey in 2010. The objectives were to image the structure beneath the trough and to improve the understanding of the San Andreas Fault system and earthquake hazard in the region. Funded by NSF grant OCE 0927446.本数据集为索尔顿地震成像项目（Salton Seismic Imaging Project, SSIP）的组成部分。2011年针对索尔顿海槽（Salton Trough）开展的本次勘探采集了48道多道地震（Multi-Channel Seismic, MCS）与海底地震仪（Ocean Bottom Seismometer, OBS）数据，采用了专为提升信号穿透深度定制的深水采集系统。一艘长17米的机动船拖曳着一艘30米长的驳船，勘探仪器即部署于该驳船之上。SALTON2010为2010年开展的配套勘探项目。本次勘探的目标为成像该海槽下方的地下结构，深化对圣安德烈亚斯断层系统以及该区域地震灾害风险的科学认知。本项目由美国国家科学基金会（National Science Foundation, NSF）编号为OCE 0927446的科研拨款资助。
