RV Investigator Voyage IN2016_V06 CTD Data

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V06 titled: "Sustained monitoring of the EAC: mass, heat and freshwater". The voyage took place between 29 October and 13 November, 2016 departing from Brisbane (QLD) and arriving in Brisbane. Data for 12 deployments were acquired using the Seabird SBE911 CTD unit 20, 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. The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (S.D) of 0. 0013601 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a S.D. of 0. 84677 uM. The agreement between the CTD and bottle data was good. The Biospherical photosynthetically active radiation (PAR), C-Star transmissometer and the Wetlabs ECO chlorophyll and CDOM sensors were also installed on the auxiliary A/D channels of the CTDThe 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.本记录描述了从澳大利亚海洋国家设施"调查者号"（RV Investigator）航次IN2016_V06中采集的电导率-温度-深度（Conductivity-Temperature-Depth, CTD）数据，该航次主题为"东澳大利亚海流（EAC）持续监测：质量、热量与淡水通量"。本次航次于2016年10月29日至11月13日开展，从布里斯班（昆士兰州）出发并返回布里斯班。本次任务共完成12次布放作业，使用搭载24个12升采水器的罗塞塔采水器（rosette sampler）上的Seabird SBE911型CTD单元20完成数据采集。采用Seabird提供的校准因子计算压力值与初始电导率数值，温度数据则使用澳大利亚联邦科学与工业研究组织（CSIRO）提供的校准方案进行校正。数据经过自动质量控制流程，以剔除尖峰噪声与超范围数值。最终电导率校准基于单次布放组完成，主传感器的最终校准标准差（S.D.）为0.0013601 实用盐度单位（PSU），优于我们设定的"优于0.002 PSU"的目标阈值。研究团队使用主传感器数据生成了1分巴（dbar）分箱平均的标准产品。溶解氧数据的校准拟合标准差为0.84677 微摩尔（uM），CTD数据与采水瓶采样数据的一致性良好。此外，CTD的辅助模数转换（A/D）通道还搭载了生物光学（Biospherical）光合有效辐射（Photosynthetically Active Radiation, PAR）传感器、C-Star透射仪以及Wetlabs公司的ECO型叶绿素与有色溶解有机物（CDOM）传感器。采集完成的数据随后经过标准化处理，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）海洋与大气科学部（Oceans and Atmosphere, O&A）信息与数据中心（Information and Data Centre, IDC）。有关该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。
