RV Investigator Voyage IN2017_C02 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2017_C02, titled: "RAN Hydrographic Survey." The voyage took place between May 4 and May 15, 2017 departing from Hobart (TAS) and arriving in Bell Bay (TAS).Only the RDI Ocean Surveyor 75kHz ADCP was operated for the voyage. Data quality is acceptable, but not ideal as the drop keep was flush with the gondola for most of the voyage. See report for full details. Data was collected during IN2017_C02 for parts of the voyage, however, gaps in the data occur at times when multibeam surveys were conducted. Data was collected using UHDAS and post-processed using CODAS.The RDI Ocean Surveyor 150kHz ADCP was not operational during this voyage. The RDI Ocean Surveyor 75kHz ADCP was run in narrowband mode. Internal triggering was used.The drop keel was at 1.19m below the waterline for most 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.本记录描述了依托澳大利亚海洋国家设施"调查者号"（RV Investigator）航次IN2017_C02所采集的声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）数据，该航次标题为"RAN水文测量"（RAN Hydrographic Survey）。本次航次于2017年5月4日至5月15日期间执行，从塔斯马尼亚州霍巴特（Hobart, TAS）起航，最终抵达塔斯马尼亚州贝尔贝（Bell Bay, TAS）。本次航次仅部署了RDI Ocean Surveyor 75kHz型号ADCP。由于航次大部分时段内可收放龙骨与ADCP吊舱平齐，数据质量尚可但未达理想水平，完整细节请参阅相关报告。本航次IN2017_C02的部分时段采集了上述数据，但在开展多波束测量期间，数据存在间隙。数据采集采用UHDAS软件，后处理采用CODAS软件。本次航次中，RDI Ocean Surveyor 150kHz型号ADCP未投入使用；RDI Ocean Surveyor 75kHz型号ADCP工作于窄带模式，并采用内部触发机制。航次大部分时段内，可收放龙骨位于吃水线以下1.19米处。有关数据采集的更多细节，请参阅航次计算与电子设备报告。本数据集已完成处理，并归档于位于霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气（Oceans and Atmosphere, O&A）信息与数据中心（IDC）。
