Multichannel minisparker, multichannel boomer, and chirp seismic-reflection data of USGS field activity 2017-612-FA collected in Puget Sound and Lake Washington in February of 2017

High-resolution multichannel minisparker, multichannel boomer and chirp seismic-reflection data were collected by the U.S. Geological Survey and the University of Washington in February of 2017 west of Seattle in Puget Sound and in Lake Washington, Washington. Data were collected aboard University of Washington's R/V Clifford A. Barnes during USGS field activity 2017-612-FA. Sub-bottom acoustic penetration spans several hundreds of meters and is variable by location. Data were collected to characterize recent deformation and estimate earthquake recurrence on the Seattle Fault zone. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

2017年2月，美国地质调查局（U.S. Geological Survey，USGS）与华盛顿大学（University of Washington）在西雅图以西的普吉特海湾（Puget Sound）及华盛顿州华盛顿湖（Lake Washington）海域采集了高分辨率多通道小火花震源（minisparker）、多通道电脉冲震源（boomer）及啁啾地震反射数据。本次数据采集工作依托华盛顿大学的R/V克利福德·A·巴恩斯号研究船开展，隶属于美国地质调查局野外作业项目编号2017-612-FA。该数据集的水底声学穿透深度可达数百米，且因采集区域不同存在显著差异。数据采集的核心目标为刻画西雅图断裂带的近期形变特征，并估算该断裂带的地震复发周期。本数据集及配套信息面向科研人员、中小学至高等院校学生、政策制定者及普通公众开放共享。
