RV Investigator Voyage IN2017_V03 EK60 Echosounder

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2017_V03, 'Sampling the abyss: latitudinal biodiversity patterns along the base of Australia’s eastern continental margin' which departed Bell Bay on the 15 May 2017 and returned to Brisbane on the 16 June 2017. The Simrad EK60 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data when possible. All frequencies were logged mainly when transitting between sites as all ship acoustics were turned off when listening for beacon signals on most operations.Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 45.5 GB of raw data in this dataset.Amy Nau, will be processing 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.

本记录记述了"RV Investigator"号科考调查船IN2017_V03航次采集的科学级分裂波束回声测深仪（split-beam echosounder）数据。该航次主题为"采样深渊：澳大利亚东部大陆边缘基底的纬度生物多样性模式"，于2017年5月15日从贝尔湾启航，2017年6月16日返回布里斯班。本次航次搭载Simrad EK60型分裂波束回声测深仪，覆盖18、38、70、120、200及333 kHz频段，在作业可行范围内采集声学背散射数据。鉴于多数作业环节需关闭船载声学设备以侦听信标信号，因此全频段声学数据主要在各科考站点间的航行时段进行记录。该数据集的原始数据以*.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），总原始数据容量达45.5 GB。本数据集将由Amy Nau负责后续处理工作。有关本数据集的更多详细信息可查阅《GSM数据采集与处理报告》。此外，其他衍生数据产品可根据申请按需获取。
