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.
