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The processed data has been archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).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.

本记录描述了从海洋国家设施（Marine National Facility, MNF）的RV Investigator"调查者号"科考船航次IN2024_T01采集的CTD（温盐深仪，Conductivity, Temperature, Depth）数据，航次标题为"弗里曼特尔至霍巴特2024年航渡"。该航次于2024年3月9日至2024年3月20日期间实施，从西澳大利亚州弗里曼特尔港启航，最终返回塔斯马尼亚州霍巴特港。

本次航次共完成7次CTD布放作业，所用设备为Sea-Bird SBE9+V2型CTD单元#24（序列号S/N 1354），其配套的罗塞塔采样器搭载了36个12升采水瓶。数据处理时采用Sea-Bird原厂提供的校准系数计算压力与初始电导率值，温度数据则应用了澳大利亚联邦科学与工业研究组织（CSIRO）提供的校准方案。所有数据均经过自动化质量控制（Quality Control, QC）流程，以剔除尖峰异常值与超范围数据。

额外搭载的传感器包括：Tritech PA500型高度计、Wetlabs C-Star型透射仪、有色可溶性有机物（Colored Dissolved Organic Matter, CDOM）传感器、叶绿素-a传感器以及Wetlabs ECO FLCDRTD型散射仪，上述设备均接入CTD的辅助模数（A/D）转换通道。

经处理后的数据集已由澳大利亚联邦科学与工业研究组织（CSIRO）国家海洋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）完成归档。有关本数据集的更多补充信息，可查阅航次总结报告与CTD数据处理报告。
