RV Investigator Voyage IN2019_V05 CTD Data

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2019_V05, titled: "Integrated Marine Observing System: monitoring of East Australian Current property transports at 27 degrees South." The voyage took place between September 9 and September 29, 2019 departing from Brisbane (QLD) and arriving in Brisbane.Data for 28 deployments were acquired using the Sea-Bird SBE911 CTD #25, fitted with 24 twelve litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.A Biospherical PAR, Tritech Altimeter, C-Star Transmissometer, WET Labs CDOM, WET Labs ECO Scattering, and WET Labs ECO Chlorophyll sensor, were also installed on the auxiliary A/D channels of the CTD.The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

本记录记述了澳大利亚国家海洋设施“调查者号”（RV Investigator）航次IN2019_V05所采集的电导率-温度-深度（Conductivity-Temperature-Depth, CTD）数据，该航次的标题为《综合海洋观测系统：南纬27度东澳大利亚海流属性输运监测》。本次航次于2019年9月9日至9月29日执行，从布里斯班（昆士兰州）出发并最终返回布里斯班。
本次共完成28次站位布放，采集数据所用设备为Sea-Bird SBE911型CTD#25，其罗式采水器搭载24个12升容积的采水瓶。采用Sea-Bird提供的校准系数计算压力与初始电导率数值；温度数据则使用CSIRO提供的校准方案进行校正。所有数据均经过自动化质量控制（Quality Control, QC）处理，以剔除尖峰噪声与超限数值。
CTD的辅助模数转换（Analog-to-Digital, A/D）通道还搭载了以下辅助传感器：Biospherical公司光合有效辐射（Photosynthetically Active Radiation, PAR）传感器、Tritech公司高度计、C-Star型透射仪、WET Labs公司有色溶解有机物（Colored Dissolved Organic Matter, CDOM）传感器、WET Labs公司ECO散射传感器以及WET Labs公司ECO叶绿素传感器。
采集所得数据随后完成处理与归档，存储于位于霍巴特的CSIRO海洋与大气（Oceans and Atmosphere, O&A）信息与数据中心（Information and Data Centre, IDC）。有关本数据集的更多详细信息，可参阅《航次总结报告》与《CTD数据处理报告》。
