RV Investigator Voyage IN2017_T02 ME70 Multibeam Fisheries Echosounder Data

This record describes ME 70 scientific multibeam fisheries echosounder data collected on RV Investigator voyage IN2017_T02, 'Collaborative Australian Postgraduate Sea Training Alliance Network (CAPSTAN): Training the Next Generation of Marine Scientists'. The voyage took place between November 14 and November 26, 2017 departing from Fremantle (WA) and arriving in Hobart (TAS). The Simrad ME70 scientific multibeam echosounder acquired acoustic backscatter data through the water column. The echosounder's frequency range is from 70 kHz to 120 kHz. Only four ME70 files were logged in testing.Data are stored in Simrad *.all raw format at CSIRO. There are 4 files totalling 318 MB of raw data in this dataset.No processing has been conducted on this data.Additional information regarding this dataset, including the settings used, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.

本记录描述了搭载于“探索者号”（RV Investigator）科考航次IN2017_T02期间采集的Simrad ME70科学多波束渔业回声测深数据，该航次主题为“澳大利亚研究生海洋培训联合联盟（CAPSTAN）：培养下一代海洋科学家”。本次航次于2017年11月14日至11月26日开展，从西澳大利亚州弗里曼特尔起航，最终抵达塔斯马尼亚州霍巴特。Simrad ME70科学多波束回声测深仪采集了水体中的声学背散射数据，其工作频率范围为70 kHz至120 kHz。测试阶段仅记录了4个ME70格式的数据文件。数据以Simrad *.all原始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4个文件，总原始数据量达318 MB，且未经过任何处理。有关本数据集的额外信息（包括所用参数设置）均收录于GSM数据采集与处理报告中。如需获取额外数据产品，可提出申请。
