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_V05, titled: "How does a standing meander southeast of Tasmania brake the Antarctic Circumpolar Current?" The voyage took place from Hobart (TAS) to Hobart between October 16 and November 16, 2018.
Data for 10 deployments were acquired using the Seabird SBE911 CTD 25 over 33 separate legs or sections. 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, 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, ECO Triplet, Nitrate, Fluorescence and LOPC were mounted on the Triaxus as attached payloads.
The standard product of 1 decibar/10 second binned averaged were produced using data from the primary sensors to produce an along-track time-series dataset. Vertical casts with interpolated values from the along the track using this binned data was also produced with a search distance of 2 casts. This generated the vertical cast and along-track section data products for each Triaxus tow.
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.
