Filtered Acoustic Backscatter and Swath Bathymetry Data from the Aleutians GeoPRISMS Focus Site acquired during R/V Marcus G. Langseth expedition MGL1110 (2011)

This data set was acquired with a Kongsberg Maritime EM122 Multibeam Sonar during R/V Marcus G. Langseth expedition MGL1110 conducted in 2011 (Chief Scientist: Dr. Donna Shillington, Investigators: Dr. Donna Shillington, Dr. Anne Becel, Dr. Mladen Nedimovic, Dr. Spahr Webb, Jiyao Li, Harold Kuehn, Dr. Matthias Delescluse, Dr. John Diebold). These data files are of MBSystem-compatible format and include Acoustic Backscatter and Swath Bathymetry data that were processed with light automatic cleaning for spikes and extreme slopes after acquisition. Data were acquired as part of the project: Megathrust seismic hazards by reflection mapping. Funding was provided by NSF award: OCE09-26614.

本数据集采集自2011年执行的“马库斯·G·兰塞斯”号（R/V Marcus G. Langseth）科考航次MGL1110，所用设备为康士伯海事（Kongsberg Maritime）EM122多波束声呐系统。本航次首席科学家为唐娜·希林顿（Donna Shillington）博士，研究团队成员包括唐娜·希林顿博士、安妮·贝塞尔（Anne Becel）博士、姆拉登·内德莫维奇（Mladen Nedimovic）博士、斯帕尔·韦伯（Spahr Webb）博士、李吉尧（Jiyao Li）、哈罗德·库恩（Harold Kuehn）、马蒂亚斯·德莱克吕斯（Matthias Delescluse）博士以及约翰·迪博尔德（John Diebold）博士。本数据集采用MBsystem兼容格式存储，包含声学背散射（Acoustic Backscatter）与条带测深（Swath Bathymetry）两类数据，采集完成后已针对尖峰噪声与极端坡度异常开展轻量自动清洗处理。本数据集为“基于反射制图的逆冲断层地震灾害研究（Megathrust seismic hazards by reflection mapping）”项目的组成部分，资助由美国国家科学基金会（National Science Foundation，NSF）OCE09-26614号项目提供。
