RV Investigator Voyage IN2015_E05 EK60 Echosounder

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage, IN2015_E05, which departed Hobart 2015-05-01 and returned on 2015-05-05.The Simrad EK60 split beam echosounders, 18, 38, 70 120, 200 and 333 kHz were used to acquire data. All frequencies were logged for the extent of the voyage. KSync settings were tested for interference with all the ship board acoustic instruments. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 66 files totalling 785 MB of raw data in this dataset.No processing has been conducted on this data.Additional information regarding this dataset is contained in the GSM data acquisition and processing report. Additional data products may be available on request.本数据集记录了“调查者号”（RV Investigator）科考航次IN2015_E05期间采集的科学用分裂波束回声测深数据。该航次于2015年5月1日从霍巴特启航，2015年5月5日返航。本次数据采集使用Simrad EK60型分裂波束回声测深仪，工作频率涵盖18、38、70、120、200及333 kHz，全航次期间对所有频率的信号均完成记录。已针对KSync设置与船上所有声学仪器的干扰情况开展测试。数据以*.raw、*.bot及*.idx格式存储于澳大利亚联邦科学与工业研究组织（CSIRO）。本数据集共包含66个文件，原始数据总容量达785 MB，且未经过任何处理。有关本数据集的更多信息收录于《GSM数据采集与处理报告》。如需获取额外数据产品，可提出申请。
