RV Investigator Voyage IN2018_V05 CTD Data

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2018_V05, titled: "How does a standing meander south-east 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 77 deployments were acquired using the Seabird SBE911 CTD unit 24, fitted with 36 twelve litre bottles on the rosette sampler. Samples were collected on all casts. Sea-Bird-supplied and CSIRO calibration factors were used to compute the pressures and preliminary conductivity, oxygen and temperature data. Automated QC was applied to the data to remove spikes and out-of-range values.A Biospherical photosynthetically active radiation (PAR), Wetlabs transmissometer and Chelsea fluorometer were installed on the auxiliary A/D channels of the CTD. Two altimeters, a serial IMU and the LADCP unit was also attached to the rosette for all casts. A high resolution magnetometer/accelerometer to assist processing the LADCP data was attached to the frame, supplied by the University of Columbia, it was logging internally and the data downloaded to the ~\in2018_v05\science\CTD\Magnetometer folder in the voyage record.The collected data were subsequently processed and 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 CTD Data Processing Report.
