Brief description
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_V03, titled: "Integrated Marine Observing System: monitoring of East Australian Current property transports at 27oS." The voyage took place from Brisbane (QLD) to Brisbane between April 19 and May 10, 2018.CTD, Dissolved Oxygen, Transmissometer, PAR, and ECO Triplet have been processed and are made available via the links below.
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.

Processing Comments from Triaxus Processing Report:
Data for 6 Triaxus deployments were acquired in Seasave CTD acquisition software using the Seabird SBE911 CTD 23. 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, FIRe 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.
