RV Investigator Voyage IN2018_T01 Triaxus (undulating CTD) Data

This record describes the data (CTD, Dissolved Oxygen, Transmissometer, PAR, ECO Triplet, Nitrate, Fluorescence and LOPC) collected using the towed TRIAXUS platform on Investigator voyage IN2018_T01, titled: "Physical and biogeochemical gradients in the East Australian Current." The voyage took place between April 6 and April 14, 2018 departing from Hobart (TAS) and arriving in Brisbane (QLD).Data for 2 Triaxus deployments were acquired in CAP CTD acquisition software using the Seabird SBE911 CTD 23. The deployments were conducted with a standard tow speed of between 7 to 10 knots and wire out ranged from 600 to 1740 m. Second deployment ended early due to loss of fibre communications.Dissolved oxygen sensors, Transmissometer and Cosine Photosynthetically Active Radiation (PAR) sensor were also installed on the auxiliary A/D channels of the CTD. In addition to the auxiliary channels, ECO Triplet, Nitrate and LOPC were mounted on the Triaxus as attached payloads.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 Data Processing Report.

本数据集记录了“‘调查者’号（Investigator）航次IN2018_T01”中利用拖曳式TRIAXUS平台采集的观测数据，本次航次主题为《东澳大利亚海流物理与生物地球化学梯度》，采集数据涵盖CTD（电导-温度-深度，Conductivity-Temperature-Depth）数据、溶解氧（Dissolved Oxygen）数据、透射仪（Transmissometer）数据、余弦型光合有效辐射（Photosynthetically Active Radiation, PAR）数据、ECO三联仪（ECO Triplet）数据、硝酸盐（Nitrate）测量数据、荧光仪（Fluorescence）数据与激光光学粒子计数器（Laser Optical Particle Counter, LOPC）数据。本次航次于2018年4月6日至4月14日开展，从塔斯马尼亚州霍巴特港启航，最终抵达昆士兰州布里斯班港。
本次任务共完成2次TRIAXUS平台布放，采用海鸟（Seabird）SBE911型CTD 23设备，通过CAP CTD采集软件完成数据获取。布放作业的标准拖曳速度为7至10节，下放缆绳长度范围为600至1740米。第二次布放因光纤通信中断提前终止。
除CTD的辅助A/D通道外，平台还搭载了溶解氧传感器、透射仪与余弦型光合有效辐射传感器。此外，ECO三联仪、硝酸盐分析仪与激光光学粒子计数器作为附加载荷安装于TRIAXUS平台之上。
采集得到的所有数据后续均已完成处理，并归档于澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）位于霍巴特的海洋与大气（Oceans and Atmosphere, O&A）信息与数据中心（Information and Data Centre, IDC）。
