Full 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 IN2019_V02, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania; Subantarctic Biogeochemistry of Carbon and Iron, Southern Ocean Time Series Site". The voyage took place from Hobart (TAS) to Hobart (TAS) between 14th March to 4th April, 2019.

Data for 3 Triaxus deployments were acquired in CAP CTD acquisition software using the Seabird SBE911 CTD 20. The deployments were conducted with a standard tow speed of between 7 to 9 knots and wire out ranged from 1050 to 1210 m.

During the first two deployments, we encountered issues with the Transmissometer and biofouling of sensors. On the second deployment a communications issue was also addressed.

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
