Shipboard EK60 - Fisheries Acoustics backscatter data, Arctic Integrated Ecosystem Research Program, Chukchi Sea 2019

These data are part of the Arctic IES component of the Arctic Integrated Ecosystem Research Program (IERP), sponsored by the North Pacific Research Board (NPRB), Collaborative Alaskan Arctic Studies Program (formerly the North Slope Borough/Shell Baseline Studies Program), Bureau of Ocean Energy Management (BOEM), and the Office of Naval Research Marine Mammals and Biology Program. To investigate the distribution, life history, and interactions of biological communities in the U.S. Continental Region of the NE Chukchi Sea a survey was conducted from August - September 2019. Acoustic backscatter was collected at 38 and 120 kHz along survey transects. This dataset contains a filtered 38 kHz dataset to represent scattering from fishes. Data is integrated into 5-meter depth bins and .1 nautical mile transect segments, and presented here in CSV format with interval, depth, and GPS identifiers.

本数据集为北太平洋研究委员会（North Pacific Research Board, NPRB）、阿拉斯加北极合作研究项目（前身为北坡自治市/壳牌基线研究项目）、海洋能源管理局（Bureau of Ocean Energy Management, BOEM）以及海军研究办公室海洋哺乳动物与生物学项目资助的北极综合生态系统研究计划（Arctic Integrated Ecosystem Research Program, IERP）的北极IES组分的一部分。为探究美国东北楚科奇海大陆区生物群落的分布特征、生活史及种间相互作用，研究团队于2019年8月至9月开展了综合科考调查。调查期间沿采样航带采集了38 kHz与120 kHz频段的声学背散射数据。本数据集包含经滤波处理的38 kHz数据集，用于表征鱼类的声学散射信号。数据已整合为5米深度分层与0.1海里航段的统计单元，并以CSV格式发布，数据包含采样间隔、深度及GPS标识信息。
