Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. Data processing and quality control by the MNF Data Acquisition and Processing Group (DAP). Data archived by CSIRO O&A - IDC. Processing Comments from Triaxus Processing Report: Data for 5 Triaxus deployments were acquired in CAP CTD acquisition software using the Seabird SBE911 CTD 25. The deployments were conducted with a standard tow speed of between 7 to 10 knots and wire out ranged from 1100 to 1250 m. Sea-Bird-supplied calibration factors and CSIRO supplied calibrations were used to compute the pressures, conductivity and temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. 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 standard data product (1 decibar/10 second binned averaged) was produced using data from the secondary sensors to produce an along-track time-series dataset for each CAP scan files. These scan files were grouped into legs, each containing a section of the Triaxus deployment and in each leg, vertical casts were created with interpolated values from the along-track time-series binned dataset with a maximum interpolation distance of 3 casts. These generated the along-track and vertical cast section data products for each Triaxus deployment. Credit Triaxus data processed by Francis Chui (CSIRO O&A). 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_V04, titled: "Constraining external iron inputs and cycling in the southern extension of the East Australian Current." The voyage took place between September 11 and October 8, 2018 departing from Hobart (TAS) ...
