Multibeam bathymetry, acoustic backscatter, and multichannel minisparker seismic-reflection data of USGS field activity 2016-666-FA collected in the Santa Barbara Basin in September and October of 2016

High-resolution multichannel minkisparker seismic-reflection (MCS) profiles were collected by the U.S. Geological Survey in September and October of 2016 from the northern portion of the Santa Barbara Basin offshore southern California. Data were collected aboard the USGS R/V Parke Snavely and NOAA R/V Shearwater during field activity 2016-666-FA. Data were acquired to support USGS geologic hazards projects to aide hazard assessment within the Santa Barbara Basin. High-resolution multichannel minisparker seismic-reflection, multibeam-bathymetry and acoustic-backscatter data were collected to investigate the causes and consequences of submarine landslides in the Santa Barbara Basin. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

2016年9月至10月，美国地质调查局（U.S. Geological Survey, USGS）于南加州近海圣巴巴拉盆地北部海域采集了高分辨率多道明斯帕克（minisparker）地震反射（Multichannel Seismic, MCS）剖面数据。本次数据采集依托美国地质调查局“帕克·斯纳夫利号”（R/V Parke Snavely）与美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）“剪水号”（R/V Shearwater）两艘研究船开展，隶属于野外作业项目2016-666-FA。本次数据采集旨在支撑美国地质调查局地质灾害研究项目，辅助开展圣巴巴拉盆地内的灾害评估工作。此次采集的数据集包含高分辨率多道明斯帕克地震反射数据、多波束测深数据与声学背散射数据，用于探究圣巴巴拉盆地海底滑坡的成因与影响。本数据集及相关信息面向科学研究人员、中小学至高等院校学生、政策制定者以及普通公众开放。
