RV Investigator Voyage IN2024_T01 CTD Data

This record describes CTD data collected from the Marine National Facility (MNF) RV Investigator voyage IN2024_T01, titled: "Freemantle to Hobart, 2024 Transit". The voyage took place between 9 March 2024 and 20 March 2024, departing from Freemantle (WA) and returning to Hobart (TAS).Data for 7 CTD deployments were acquired using the Sea-Bird SBE9+V2 CTD unit #24 (S/N 1354), fitted with 36 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.Additional sensors include: Altimeter (Tritech PA500), Transmissometer (Wetlabs C-Star ), CDOM, Chlorophyll-a, Scattering (Wetlabs ECO FLCDRTD) were installed on the auxiliary A/D channels of the CTD.The processed data has been archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

本记录描述了源自海洋国家设施（Marine National Facility, MNF）“探索者号”（RV Investigator）航次IN2024_T01的温盐深仪（Conductivity, Temperature, Depth, CTD）数据，该航次标题为“弗里曼特尔至霍巴特，2024年过境航次”。本航次执行时间为2024年3月9日至2024年3月20日，从西澳大利亚州弗里曼特尔（WA）出发，最终返回塔斯马尼亚州霍巴特（TAS）。
本次共完成7次CTD布放作业，数据采集采用海鸟（Sea-Bird）公司SBE9+V2型CTD设备#24（序列号1354），该设备的罗塞特采水器搭载了36个12升采水瓶。采用海鸟（Sea-Bird）公司提供的校准系数计算压力与初始电导率值；温度数据则使用联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）提供的校准方案进行校正。已对数据执行自动化质量控制（Quality Control, QC），以剔除尖峰噪声与超限值。
附加传感器包括安装于CTD辅助模数转换（Analog-to-Digital, A/D）通道的高度计（Tritech PA500）、透射率计（Wetlabs C-Star）、有色溶解有机物（Colored Dissolved Organic Matter, CDOM）、叶绿素a（Chlorophyll-a）以及散射传感器（Wetlabs ECO FLCDRTD）。
经处理后的数据集已由联邦科学与工业研究组织国家馆藏与海洋基础设施（National Collections and Marine Infrastructure, NCMI）信息与数据中心（Information and Data Centre, IDC）归档保存。有关本数据集的补充信息可参阅航次总结报告与CTD数据处理报告。
