Chirp seismic-reflection data of field activity S-07-11-SC: offshore San Diego, and Los Angeles Counties, southern California from 2011-06-08 to 2011-06-22

This dataset includes raw and processed, high-resolution seismic-reflection data collected in 2011 to collect information on active offshore faults. The survey area is offshore southern California between Long Beach and San Diego. The data were collected aboard the U.S. Geological Survey R/V Parke Snavely. The seismic-reflection data were acquired using an EdgeTech 512 subbottom profiler. Subbottom acoustic penetration spanned tens to about 50 meters, variable by location.

本数据集涵盖2011年采集的原始及经处理的高分辨率地震反射（seismic-reflection）数据，用于获取近海活动断层的相关信息。勘探区域位于美国加利福尼亚州南部近海，介于长滩（Long Beach）与圣迭戈（San Diego）之间。本次数据采集工作由美国地质调查局（U.S. Geological Survey）的R/V Parke Snavely号科考船完成。此次地震反射数据采用EdgeTech 512型浅地层剖面仪（subbottom profiler）采集，海底浅层声波穿透深度可达数十米至约50米，具体数值因勘探位置而异。
