Chirp seismic-reflection data of field activity 2014-645-FA; Santa Cruz Basin offshore Santa Barbara, southern California from 2014-11-12 to 2014-11-25

This data release contains high-resolution seismic-reflection data collected in 2014 to explore to explore marine geologic hazards offshore of southern California. Specific targets include the San Clemente, Catalina, and Catalina Ridge faults in the Catalina Basin, and a submarine landslide complex observed in multibeam bathymetry images in the Santa Cruz Basin. The survey took place in the Santa Cruz and Catalina Basins offshore of Ventura, California. The data were collected aboard the Scripps Institution of Oceanography R/V Robert Gordon Sproul. The seismic-reflection data were acquired using a hull-mounted Knudsen 320B echosounder. Subbottom acoustic penetration spans up to several tens of meters, and is variable by location. This data release contains processed digital SEG-Y.本数据集发布内容包含2014年采集的高分辨率地震反射数据，用于探查加利福尼亚南部近海的海洋地质灾害。本次勘探的具体目标包括卡特琳娜盆地（Catalina Basin）内的圣克莱门特（San Clemente）断层、卡特琳娜（Catalina）断层与卡特琳娜岭（Catalina Ridge）断层，以及圣克鲁斯盆地（Santa Cruz Basin）内多波束测深（multibeam bathymetry）图像中观测到的海底滑坡复合体。本次勘探作业实施于加利福尼亚州文图拉近海的圣克鲁斯盆地与卡特琳娜盆地。数据采集工作由斯克里普斯海洋研究所（Scripps Institution of Oceanography）的R/V罗伯特·戈登·斯普罗尔号考察船完成。地震反射数据采用安装于船体的克努森（Knudsen）320B型回声测深仪采集。海底声学穿透深度可达数十米，且随测点位置不同而存在差异。本数据集包含经过处理的数字SEG-Y格式地震数据。
