				Abstract 
        
        
	<a title='This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2023_V04, titled: "International nutrient inter-comparison study in the Southern Ocean: quantifying and identifying the causes of differences in dissolved inorganic nutrient datasets between global seagoing laboratories - Phase 2." The voyage took place between June 5, 2023 and June 18, 2023 (AEST), departing from Hobart and returning to Hobart. The OS150 unit was run for the majority part of the voyage. The OS75 was running with three beams for the duration of the voyage. Experts at University of Hawaii determined that the fourth beam is broken and will require servicing by RDI to rectify. Additionally, some electrical noise was observed, to be further investigated when returning to port. Acceptable data was obtained using the three-beam solution, with a slightly compromised range of around 600m. It is recommended that the OS75 is operated as normal for all upcoming voyages. ADCP data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS). Documentation for these systems can be found in (Hummon, 2009-2021). This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).'> <img src="/data/common/web_media/icons/help1.gif"> </a>

				Abstract 
        
        
	<a title='This record describes the ISAR/SST Sea Surface Temperature data collected on the RV Investigator Voyages from 2014 onwards. The infrared SST autonomous radiometer (ISAR) is a self-calibrating instrument capable of measuring in situ sea surface skin temperature to an accuracy of 0.1 K. The SST Radiometer is mounted on the port bridge wing, approximately 19.593m above the summer load line. The RV Investigator ISAR skin SST data are also supplied both in real-time (http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/meteorological_sst_observations/catalog.html) and in delayed mode after reprocessing (e.g., http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/meteorological_sst_observations/2016/ISAR-QC/catalog.html). These reprocessed files will be particularly valuable for satellite SST validation (as the ISAR measures SST at the same depth as measured by satellites) and are currently (2017) being used by EUMETSAT for Sentinel-3 SST validation and to JMA and Oceans University China for Himawari-8 SST validation.

	<a title='This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2023_E03, titled "Trials and Calibrations." The voyage consisted of three legs and took place between September 13, 2023 and September 30, 2023 (AEST), departing from Hobart and returning to Sydney. Standard Underway data is continuously recorded, consisting of: (1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, Course Over Ground, Gyros, and Doppler Log (dual GPS instrument). (2) Thermosalinograph (TSG): Water Salinity, Flow-Rate, Temperature, Fluorescence, pCO2 and Optode/Oxygen. (3) Atmospheric (MET): Humidity, Wind Speed and Direction (vane and ultrasonic), Radiometer/Sea Surface Temperature, Pyranometer/Solar Radiation, Photosynthetically Active Radiation (PAR), Air Temperature, Air Pressure, Rain, Ozone and Trace Gases (port and starboard instruments). The quality-controlled RV Investigator underway meteorological and SST data are supplied to the IMOS AODN and other global data repositories and distributors, and made available for satellite SST validation by the Australian Bureau of Meteorology (BoM). Near real-time, unprocessed data are available via the link "Visualisation tool for Underway Data." This dataset has been processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Data are available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII format).

	<a title='This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2023_V04, International nutrient inter-comparison Voyage (INIV) which departed Hobart on the 05/06/23 and returned to Hobart on the 18/06/23. The Simrad EK60 split beam echosounders for18kHz 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, in the Southern Ocean Southwest of Hobart. All frequencies were logged sporadically for the extent of the voyage. The 70 KHz frequency was set to passive for the periods of the voyage. Data are stored in *.raw, *.bot and *.idx format at CSIRO. There are 2,644 files totalling 59.6 GB of raw data in this dataset. No Processing has been conducted on this data.

				Abstract 
        
        
	<a title='This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2023_V04, titled: "International nutrient inter-comparison study in the Southern Ocean: quantifying and identifying the causes of differences in dissolved inorganic nutrient datasets between global seagoing laboratories - Phase 2". The voyage took place between June 5 and June 18, 2023 departing from Hobart (TAS) and returning to Hobart. Data for 10 CTD deployments were acquired using the Sea‐Bird SBE9+V2 CTD unit #24 (S/N 1332), 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 secondary sensor had a standard deviation (SD) of 0.0010067 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1‐decibar binned averages were produced using data from the secondary sensors. The dissolved oxygen data calibration fit had a SD of 0.92376 μM. The agreement between the CTD and bottle data was good. The collected data were subsequently processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

The voyage took place between June 28, 2023 and July 30, 2023 (AEST), departing from Hobart and returning to Hobart. The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 14 files totalling 205 MB of raw data in this dataset. A wharf tie was not undertaken due to the sensor replacements, and malfunctions. Gravity data was acquired for adhoc periods throughout the voyage although due to continued errors, malfunctions and swapping of sensor hardware it is recommended this data not be published. The manufacturer advised the systems control module be replaced as a potential solution to malfunctions. This was carried out on the 3rd July 2023. The system was observed to similarly malfunction after a short period.
