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 IN2022_V06, titled: "Integrated Marine Observing System: Monitoring of East Australian Current property transports at 27 degrees South." The voyage took place between July 14 to July 29, 2022 departing from Brisbane (QLD) and returning to Brisbane. 5 Triaxus tows were conducted to study the spatiotemporal variability of water on the shelf near the Stradbroke Island National Reference Station (NRS), characterise shelf boundary exchanges, and sample eddies coming from the waters around Fraser Island. See the IN2022_V06 voyage plan for more details. Pressure, conductivity, temperature, and dissolved oxygen data were gathered from duplicate sensors using a Seabird SBE9plus 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) and a Laser Optical Plankton Counter (LOPC). Additional MNF-supplied sensors included a Sea-Bird Scientific SUNA V2 nitrate sensor. The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.
