RV Investigator Voyage IN2019_V03 CTD Data

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2019_V03, titled: "A coupled bio-physical, ecosystem-scale examination of Australia’s International Indian Ocean Expedition Line." The voyage took place between May 13 and June 14, 2019 departing from Fremantle (WA) and arrivfing in Fremantle.

Data for 54 deployments were acquired using the Sea-Bird SBE911 CTD #23 and #24, fitted with 36 twelve litre bottles on the rosette sampler. CSIRO-supplied calibrations factors were used to compute the pressures, temperature and preliminary conductivity values. The data were subjected to automated QC to remove spikes and out-of-range values.

Chelsea Fluorometer, PAR Sensor, Altimeter, Wetlabs Transmissometer, UVP were also installed on the auxiliary A/D channels of the CTD. Additionally a Teledyne LADCP was installed on 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.

本记录记述了从澳大利亚国家海洋设施“调查者号”（RV Investigator）航次IN2019_V03获取的温盐深（Conductivity-Temperature-Depth, CTD）数据，航次主题为“澳大利亚国际印度洋考察航线的生物-物理耦合生态系统尺度研究”。该航次于2019年5月13日从西澳大利亚州弗里曼特尔起航，同年6月14日返回弗里曼特尔。

本次共完成54次CTD布放作业，所用设备为Sea-Bird SBE911型CTD 23号与24号单元，采水器挂架搭载36个12升采水瓶。本数据集采用澳大利亚联邦科学与工业研究组织（CSIRO）提供的校准因子计算压力、温度及初始电导率数值，并经自动化质量控制流程剔除尖峰噪声与超范围异常值。

CTD系统的辅助模数转换（A/D）通道还搭载了切尔西荧光计、光合有效辐射（PAR）传感器、高度计、Wetlabs透射仪以及水下视觉剖面仪（UVP）。此外，CTD系统集成了特莱迪尼（Teledyne）LADCP设备。

所采集的数据经后续处理后，归档于位于霍巴特的澳大利亚联邦科学与工业研究组织海洋与大气（O&A）信息与数据中心（IDC）。本数据集的更多相关信息可参阅《航次总结报告》与《CTD数据处理报告》。
