Chirp seismic-reflection data collected offshore of San Diego and Los Angeles Counties, southern California, from 2011-06-08 to 2011-06-22 (USGS field activity S-7-11-SC)

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.

本数据集包含2011年采集的原始与经处理的高分辨率地震反射数据，用于获取近海活动断层的相关信息。本次调查区域位于加利福尼亚州南部近海，介于长滩（Long Beach）与圣迭戈（San Diego）之间。数据采集工作由美国地质调查局（U.S. Geological Survey）的R/V Parke Snavely号研究船完成。此次地震反射数据采用EdgeTech 512型浅地层剖面仪（subbottom profiler）采集，其浅地层声波穿透深度可达数十米至约50米，具体数值随采集点位的不同而变化。
