RV Investigator Voyage IN2018_T01 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility 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.Data was collected during IN2018_T01 for the duration of the voyage. Data was collected using UHDAS and post-processed using CODAS.The RDI Ocean Surveyor 150kHz ADCP was out of service, being replaced by a WorkHorse Quartermaster 150kHz ADCP for the duration of the voyage.The RDI Ocean Surveyor 75kHz ADCP was run in broadband mode during the port period and the first day of the voyage whilst leaving Hobart and in narrowband mode from 0016 07/04/2018 for the duration of the voyage.Internal triggering was used.The drop keel was at 2m below the waterline for most of the voyage and lowered to 4m in periods of deep water.See the voyage computing and electronics report for more details regarding data acquisition.This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart.

本记录描述了从澳大利亚国家海洋设施研究船RV Investigator考察航次IN2018_T01中采集的声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）数据，该航次的标题为《东澳大利亚海流的物理与生物地球化学梯度》。本次航次于2018年4月5日至4月14日期间开展，航行路线为从塔斯马尼亚州霍巴特前往昆士兰州布里斯班。
数据采集工作贯穿整个IN2018_T01航次全程，采用UHDAS系统进行采集，并通过CODAS软件完成后处理。
RDI Ocean Surveyor 150kHz型号ADCP在航次期间处于停用状态，由WorkHorse Quartermaster 150kHz型号ADCP替代。RDI Ocean Surveyor 75kHz ADCP在港口停泊时段及离港首日采用宽带模式运行，自2018年4月7日00:16起，全程切换为窄带模式运行。本次数据采集采用内部触发模式。
航次大部分时段，可收放龙骨被设置在水线以下2米处，在深水区域则下放至水线以下4米。
