RV Investigator Voyage IN2018_T01 EK60 Echosounder

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2018_T01, titled: "Physical and biogeochemical gradients in the East Australian Current." The voyage took place from Hobart (TAS) to Brisbane (QLD) between April 5 and April 14, 2018.

The Simrad EK60 split beam echosounders 18, 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data, between Brisbane and Hobart. All frequencies were logged sporadically for the extent of the voyage. The frequencies were set to passive for the periods of the voyage.

Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 2,175 files totalling 41.7 GB of raw data in this dataset.

No processing has been conducted on this data. Data spans 5/04/2018 20:00 until 06/04/2018 06:00 UTC.

本数据集记录了“RV Investigator”号科考船IN2018_T01航次采集的科学分裂波束回声测深仪（split-beam echosounder）数据，航次主题为《东澳大利亚海流的物理与生物地球化学梯度》。该航次于2018年4月5日至4月14日从塔斯马尼亚州霍巴特前往昆士兰州布里斯班。
本次航次使用Simrad EK60分裂波束回声测深仪的18、38、70、120、200及333 kHz频段，在布里斯班至霍巴特航线上采集声学后向散射数据；全航次期间各频段均进行间歇性记录，且全程将测深仪设置为被动模式。
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），本数据集共计2175个文件，原始数据总容量达41.7 GB。
本数据集未经过任何处理，数据覆盖时段为协调世界时（UTC）2018年4月5日20:00至2018年4月6日06:00。
