	<a title='This record describes multibeam echosounder data collected on RV Investigator voyage IN2024_V01, Multidisciplinary Investigations of the Southern Ocean which departed Hobart on 05/01/2024 and returned to Fremantle on 05/03/2024. The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter from Hobart, along the Antarctic ice edge to Fremantle. The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounders nominal frequency range is from 40 to 100 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 135 files totalling 126.9 GB of raw data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. GPS tide was computed using the EGM2008 model and applied to the processed data. Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry grids in geotiff format. Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report.

	<a title='This record describes sub bottom profiler data collected on RV Investigator voyage IN2024_V02, "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between March 31, 2024 and April 19, 2024 (AEST), departing from Hobart and returning to Hobart. The Kongsberg SBP120 (sub bottom profiler) was used to acquire data containing the specular reflections at different sediment interfaces below the seafloor. The SBP120 provides a 3° by 3° angular resolution. The echosounders frequency sweep range is from 2.5 to 7 kHz.

Data are stored in *.raw (198 files 4.26 GB) raw and *.seg (197 files 4.22 GB) segy formats at CSIRO. The segy format data had a real time processing stream applied, which applies gain, a gain correction, matched filter with replica shaping, an attribute calculation for instantaneous amplitude and time variable gain.

				Abstract 
        
        
	<a title='This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2024_T01, Transit Voyage: Fremantle to Hobart. The primary objective of the voyage was the safe and timely transit of RV Investigator from Fremantle to Hobart in preparation for the following research voyage. During the transit various research projects were conducted, along with outreach, familiarisation and training activities. The voyage departed Fremantle on the 09 March and returned to Hobart on the 20 March. The Simrad EK60 split beam echosounders for 18kHz and Simrad EK80 split beam echosounders for 38, 70 120, 200 and 333 kHz were used to acquire acoustic backscatter data to a range of 1500 m, between Fremantle and Hobart. All frequencies were logged continuously for the extent of the voyage with the excpetion of the 70 kHz which was set to passive for the periods of focused seafloor mapping. While the 18 kHz was used and recorded for the voyage, it should not be used for quantitative analysis due to a damaged transducer channel. The transducer is planned to be replaced during the vessels mid-life. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 2161 files totalling 50.2 GB of raw data in this dataset. No processing has been conducted on this data. Additional information regarding this dataset is contained in the GSM data acquisition and processing report.

	<a title='This record describes multibeam echosounder data collected on RV Investigator voyage IN2024_V02, "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between March 31, 2024 and April 19, 2024 (AEST), departing from Hobart and returning to Hobart. The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter between Hobart and Southern Ocean Time Series mooring. The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounders nominal frequency range is from 40 to 100 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 31 files totaling 5.87 GB of raw bathymetry and backscatter and 31 files totaling 39.5 GB of raw watercolumn backscatter data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. GPS tide was computed using the EGM2008 model and applied to the processed data. Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry grids in geotiff format. Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report.

	<a title='This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2024_V01, titled: "Multidisciplinary Investigations of the Southern Ocean (MISO): Linking Physics, Biochemistry, Plankton, Aerosols, Clouds, And Climate." The voyage took place between January 2 and March 5, 2024 departing from Hobart (TAS) and returning to Freemantle (WA) Data for 103 CTD deployments were acquired using the Sea-Bird SBE9+V2 CTD unit #24 (S/N 1354), fitted with 36 twelve-litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.0012679 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the primary sensors. The dissolved oxygen data (primary) calibration fit had a SD of 0.94146 (Casts: 1-52) and 0.94773 (Casts: 53-103) μM. The agreement between the CTD and bottle data was good. Additional sensors include: Altimeter (Tritech PA500), Transmissometer (Wetlabs C-Star ), CDOM, Chlorophyll-a, Scattering (Wetlabs ECO FLCDRTD) were installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed (quality-controlled), and 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 CTD Data Processing Report.'> <img src="/data/common/web_media/icons/help1.gif"> </a>
