RV Investigator Voyage IN2019_V07 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 IN2019_V07, titled: "RAN Hydrographic and Maritime Heritage Surveys." The voyage took place between April 11 and April 23, 2019 departing from Hobart (TAS) and arriving in Hobart. Data for 2 Triaxus tows were acquired using Seabird’s Seasave acquisition software using the Seabird SBE911+ CTD 24. O&A Calibration lab supplied calibration factors were used to compute the pressure, preliminary conductivity, oxygen and temperature values. The data was subjected to automated QC to remove spikes and out-of-range values.A Transmissometer and a Cosine Photosynthetically Active Radiation (PAR) sensor were also installed on the auxiliary A/D channels of the CTD. In addition to the auxiliary channels an ECO Triplet and LOPC were mounted on the Triaxus as attached payloads. The standard data product (1 decibar/10 second binned averaged) was produced using data from the primary sensors to produce an along-track time-series dataset for each data recording file. The data from each tow were recorded as a single file. Vertical casts were created with interpolated values from the along-track time-series binned dataset with a maximum interpolation distance of 1 cast. These generated the along-track and vertical cast section data products for each Triaxus tow. Due to a cable failure the PAR and transmissometer data were unusable. The flow meter of the LOPC was suspected to be faulty, compromising the recorded data.The collected data were subsequently 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.

本记录描述了在“调查者号”（Investigator）航行IN2019_V07期间，通过拖曳式TRIAXUS平台采集的数据，包括温盐深仪（CTD）、溶解氧、透射仪（Transmissometer）、光合有效辐射（PAR）、ECO Triplet、硝酸盐、荧光和激光浮游生物计数器（LOPC）。该航行标题为“RAN水文与海洋遗产调查”，于2019年4月11日至23日进行，从霍巴特（塔斯马尼亚州，TAS）出发并返回霍巴特。

两次TRIAXUS拖曳的数据通过Seabird公司的Seasave采集软件获取，使用的设备为Seabird SBE911+ CTD 24。澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气研究所（O&A）校准实验室提供的校准因子用于计算压力、初步电导率、溶解氧和温度值。数据经过自动化质量控制（QC）处理，以去除尖峰信号和超出范围的值。

透射仪和余弦型光合有效辐射（PAR）传感器也安装在CTD的辅助模数转换（A/D）通道上。除辅助通道外，ECO Triplet和LOPC作为附加有效载荷安装在TRIAXUS平台上。标准数据产品（1分巴/10秒分箱平均）利用主传感器数据生成，为每个数据记录文件提供沿航迹的时间序列数据集。每次拖曳的数据记录为单个文件。垂直剖面通过沿航迹时间序列分箱数据集的插值生成，最大插值距离为1个剖面。这些操作生成了每次TRIAXUS拖曳的沿航迹和垂直剖面数据产品。

由于电缆故障，PAR和透射仪数据无法使用。LOPC的流量计疑似故障，导致记录的数据不可靠。

采集的数据随后归档于霍巴特的CSIRO海洋与大气研究所（O&A）信息与数据中心（IDC）。关于本数据集的更多信息可能包含在航行总结和数据处理报告中。
