RV Investigator Voyage IN2019_V05 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_V05, titled: "Integrated Marine Observing System: monitoring of East Australian Current property transports at 27 degrees South." The voyage took place between September 9 and September 29, 2019 departing from Brisbane (QLD) and arriving in Brisbane.Data for 6 Triaxus deployments were acquired using Seabird’s Seasave acquisition software using the Seabird SBE911+ CTD 23. 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 Biospherical QCP2300-HP PAR, and a WetLabs C-STAR Transmissometer sensors 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. These files were grouped into sections containing each Triaxus deployment and in each deployment, 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 deployment.All deployments except for 3 were along the mooring line transect. Throughout the voyage there were some issues with the Triaxus vehicle. Communication loss with the Triaxus ended Deployment 1 early, requiring re-termination. Deployment 5 also suffered communication loss, ending acquisition early. The Primary SBE43 Oxygen sensor was swapped out after deployment 3 due to increased noise in sensor readings.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“整合海洋观测系统：南纬27度东澳洋流属性输运监测”（Integrated Marine Observing System: monitoring of East Australian Current property transports at 27 degrees South）航次中，由“调查者”号（Investigator）执行的IN2019_V05航次里，使用拖曳式TRIAXUS平台采集的各类数据，包括温盐深仪（CTD）、溶解氧（Dissolved Oxygen）、透射率计（Transmissometer）、光合有效辐射（PAR）、ECO三联传感器（ECO Triplet）、硝酸盐（Nitrate）、荧光（Fluorescence）以及激光光学粒子计数器（LOPC）。本次航次于2019年9月9日至9月29日开展，从布里斯班（昆士兰州，QLD）出发并最终返回布里斯班。 本次航次共完成6次TRIAXUS部署，数据采集采用海鸟电子（Seabird）的Seasave采集软件，搭配Seabird SBE911+型CTD 23设备。采用O&A校准实验室提供的校准系数，计算得到压力、初始电导率、溶解氧及温度数据。对数据开展自动化质量控制（QC），以剔除尖峰噪声与超量程数值。 在CTD的辅助模数转换（A/D）通道上，还安装了Biospherical公司QCP2300-HP型PAR传感器，以及WetLabs公司C-STAR型透射率计传感器。除辅助通道外，TRIAXUS平台还搭载了ECO Triplet与LOPC作为附加载荷。 基于主传感器数据生成标准数据产品（按1分巴/10秒分箱平均），为每个数据记录文件生成沿航迹时间序列数据集。将上述文件按单次TRIAXUS部署分组，针对每组部署，利用沿航迹分箱时间序列数据集的插值数据生成垂直剖面，最大插值距离设为1个剖面。由此为每次TRIAXUS部署生成沿航迹与垂直剖面分段数据产品。 除第3次部署外，其余所有部署均沿锚系断面测线开展。航次期间TRIAXUS平台曾出现若干故障：第一次部署因与平台通信中断提前终止，需重新终止采集流程；第五次部署同样遭遇通信中断，提前结束数据采集。第三次部署后，因传感器读数噪声增大，更换了主SBE43型溶解氧传感器。 采集得到的数据随后被归档至位于霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气分部（O&A）信息与数据中心（IDC）。有关本数据集的更多信息可参阅航次总结报告与数据处理报告。
