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 the CSIRO NCMI Information and Data Centre. Credit Triaxus data processed by Richard Atkinson (CSIRO/NCMI) Credit These data were collected on the Marine National Facility (MNF) RV Investigator voyage IN2020_V08 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 IN2020_V08, titled: "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters." The voyage took place between December 4, 2020 and January 15, 2021 departing from Hobart (TAS) and arriving in Hobart. Eight Triaxus tows were undertaken. Tows 1 to 7 were to investigate oceanographic and biological features of interest to the Southern Ocean Large Areal Carbon Export project. The eighth tow was to compare to altimetry satellite data. Pressure, conductivity, temperature, and dissolved oxygen data were gathered from duplicate sensors using a Seabird SBE9+ CTD. Also carried on the Triaxus hull were a cosine Photosynthetically Active Radiation (PAR) sensor, a transmissometer, an eco-triplet (optical backscatter, CDOM fluorometer and chlorophyll fluorometer), a Laser Optical Plankton Counter (LOPC), and a user-provided Fluorescence Induction and Relaxation (FIRe) system. On each tow, only data from sections where the Triaxus was undulating regularly were processed. Data from deployment, turns and retrieval were gathered but not further processed. Pressure, conductivity, temperature, and dissolved oxygen sensor data were converted to calibrated units. Spikes and out-of-range values were removed and primary to secondary sensor data compared. Similarly PAR, transmissometer, and eco-triplet data were combined into the dataset. Both LOPC and FIRe data were gathered but are not processed or ...
