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 Processed Data Summary: Data for 2 Triaxus deployments were acquired in CAP CTD acquisition software using the Seabird SBE911 CTD 22. The deployments were conducted with a standard tow speed of between 7 to 10 knots and 1200 m wire out. 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, Fluorescence 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 CAP deployment. These deployments 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 1 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 IN2015_V01, titled: "IMOS Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between March 21 and March 30, 2015 departing from Hobart (TAS) and ...
