RV Investigator Voyage IN2020_V08 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2020_V08, titled: "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters." The voyage took place between December 4, 2020 and January 15, 2021 departing from Hobart (TAS) and arriving in Hobart.

Data was collected during IN2020_V08 for the duration of the voyage excluding short periods of time for GSM data collection, during Silent-R testing and whilst leaving port. Data was collected using UHDAS and post-processed using CODAS.

Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband. Internal triggering was used.
The drop keel was flush with the gondola when acquisition commenced, lowered to 1.25m below the waterline for 2 hours and lowered to 2m below the waterline for the remainder of the voyage.

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.

本记录详述了采集自澳大利亚海洋国家设施（Marine National Facility）"调查者号"（RV Investigator）航次IN2020_V08的声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）数据，该航次的项目标题为"SOLACE——南大洋大面积碳输出：量化亚极地与极地水域的碳封存"。本航次执行时间为2020年12月4日至2021年1月15日，起航与终靠港口均为塔斯马尼亚州霍巴特。

本次数据采集覆盖航次大部分时段，但需排除用于GSM数据采集、Silent-R测试及离港的短暂时段。数据通过UHDAS系统采集，并采用CODAS软件进行后处理。

本次实验同时部署了RDI Ocean Surveyor 150kHz与75kHz两款声学多普勒流速剖面仪，二者均工作于窄带模式，且采用内部触发机制。数据采集启动时，投放式龙骨与设备吊舱平齐；随后将其下放至吃水线以下1.25米处，持续2小时；剩余航次期间则将其下放至吃水线以下2米处。
