RV Investigator Voyage IN2019_V03 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_V03, titled: "A coupled bio-physical, ecosystem-scale, examination of Australia’s International Indian Ocean Expedition line." The voyage took place between May 14 and June 14, 2019 departing from Fremantle (WA) and arriving in Fremantle.

Data for 3 Triaxus deployments were acquired using seabirds SeaSave acquisition software with Seabird SBE911+ CTD #23.

Sea-Bird and 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.

Dissolved oxygen sensors, Photosynthetically Active Radiation (PAR) 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 and seconday sensors to produce an along-track time-series dataset for each data scan file. These files were grouped into sections/legs containing the Triaxus deployment. Moreover, for each section, 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.

Throughout the voyage there were some issues with the Triaxus deployments. As a result, the standard data products could not be made for every deployment. See the Processing Report for further details.

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_V03期间，使用拖曳式TRIAXUS平台收集的数据，包括温盐深仪（CTD）、溶解氧、透射仪、光合有效辐射（PAR）、ECO Triplet、硝酸盐、荧光和LOPC数据。该航行的标题为“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”，于2019年5月14日至6月14日进行，从西澳大利亚州弗里曼特尔（Fremantle，WA）出发并返回该地。

3次Triaxus部署的数据通过Seabird公司的SeaSave采集软件及Seabird SBE911+ CTD #23获取。

Sea-Bird与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、氧气和温度值。数据经过自动质量控制（QC）以去除尖峰和超出范围的值。

溶解氧传感器、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作为附加载荷安装在Triaxus上。

标准数据产品（1分巴/10秒分箱平均）通过主次传感器的数据生成，为每个数据扫描文件提供沿航迹时间序列数据集。这些文件被分组到包含Triaxus部署的区段/航段。此外，每个区段利用沿航迹时间序列分箱数据集的插值值生成垂直剖面，最大插值距离为1次剖面。这些插值生成了每个Triaxus部署的沿航迹和垂直剖面区段数据产品。

航行期间，Triaxus部署存在一些问题。因此，并非所有部署都能生成标准数据产品。详情请参见处理报告。

收集的数据随后存档于霍巴特的CSIRO海洋与大气（O&A）信息与数据中心（IDC）。
