This record describes the Microtops Sun Photometer data from the Marine National Facility (MNF) RV Investigator voyage IN2023_V06, titled "Understanding Eddy Interactions and Their Impacts in the East Australian Current System." The voyage took place between October 9, 2023 and November 2, 2023 (AEST), departing from Sydney and returning to Sydney.

This record describes the data collected on the RV Investigator Voyage IN2016_V05 Titled: "The Great Barrier Reef as a significant source of climatically relevant aerosol particles." The voyage took place between September 26 and October 24, 2016 departing from Brisbane (QLD) and arriving in Brisbane. Instrument Name: Microtops II Ozone Monitor- Sunphotometer, ECN # 2624374, is a hand-held multi-band sunphotometer capable of measuring the total ozone column and optionally the water vapor column (also called precipitable water) as well as aerosol optical thickness at 1020nm. Parameters measured: AOD (Aerosol Optical Depth). Data format: .xls, Owner of instrument: NASA. Further Information can be found in the data and documentation links below.

This record describes the End of Voyage (EOV) archive from the Marine National Facility RV Investigator trial voyage IN2015_E05 - Geoscience, testing equipment and developing procedures. This trial voyage took place from Hobart to Hobart departing on the 1st May and returning on the 5th May, 2015. Data collected included Acoustic Doppler Current Profiler (ADCP)-(75, 150 KHz), Underway (UWY), SST Radiometer, Atmospheric data (Absorption Photometer, Nephelometer, Ozone and Radon), Greenhouse data (Aerodyne and Picarro), Underway pCO2, Echosounders (18, 38, 70, 120, 200, 333 kHz), Multibeam (EM122, EM710, ME70 and SBP120) and XBT. The EOV paper documentation - Multibeam: EM122, EM710, SBP120, XBT Logs and GSM pre-voyage checklist, were scanned, archived and entered in the records management system TRIM, reference "in2015_e05". ELOG files were generated as .csv and archived. All voyage documentation is archived c/o the Data Centre in Hobart available electronically to MNF support via the local network "global_docs". Access to voyage documentation for non CSIRO participants can be made via DataLibrariansOAMNF@csiro.au. The archive for the IN2015_E05 EOV data will be held temporarily within the CSIRO Oceans and Atmosphere Data Centre in Hobart with a permanent archive to be located at the CSIRO Data Access Portal (DAP), providing access to participants and processors of the data collected on the Marine National Facility RV Investigator IN2015_E05

This record describes the End of Voyage archive from the Marine National Facility (MNF) RV Investigator voyage IN2015_V01 titled "IMOS Southern Ocean Time Series Automated Moorings for Climate and Carbon Cycle Studies Southwest of Tasmania". This was the first research voyage for the RV Investigator. The voyage took place between the 21st and the 30th of March, 2015 (local time) departing from Hobart and sailing to the south-west of Tasmania (47 S, 142 E) and returning to Hobart. Routine data collected included Acoustic Doppler Current Profiler (ADCP) (75, 150 KHz), Underway (UWY), SST Radiometer, CTD, Hydrology, Atmospheric data including aerosol properties, particulates and composition, ozone and radon, Greenhouse gases data, Underway pCO2, Echosounders (38, 70, 120, 200, 333 KHz), Multibeam (EM122, EM710, ME70 and SBP120) and XBT. Additional atmospheric instruments used on this voyage included two Condensation Particle Counters (CPC), Time of Flight Aerosol Chemical Speciation Monitor (ToF-ACSM), Cloud Radar BASTA 95GHz, Cloud Condensation Nuclei Counter (CCN), Long Scanning Mobility Particle Size (longSMPS), Nano Scanning Mobility Particle Size (nanoSMPS), Old Scanning Mobility Particle Size (Old SMPS), Neutral Cluster Air Ion Spectrometer (NAIS), Proton Transfer Reaction Mass Spectrometer (PTR-MS), Volatile Organic Chemical Sequencer (VOC) and Mercury Vapour Analyser (Tekran unit). Three CTD casts to 2250m with temperature, salinity, oxygen, phytoplankton fluorescence, particle backscatter, and beam attenuation sensors were sampled at 24 depths for the analyses of nutrients, salinity, Dissolved Inorganic Carbon (DIC), alkalinity and dissolved oxygen. The top 6 depths (to 150m) were also analysed for particulate organic carbon and pigments. Additional underway samples were collected for particulate organic carbon, biogenic silica, spectroscopic and pigment analyses. The towed undulating CTD (TRIAXUS) with the ECO Triplet optical sensor, Laser Optical Plankton Counter (LOPC) and the newly mounted Submersible Ultraviolet Nitrate Analyser (SUNA) and Fluorescence Induction and Relaxation (FIRe) instruments was deployed. The SAZ-16 sediment trap mooring deployed in May 2013 was recovered. Three moorings for recovery in April 2016 were deployed: SOFS-5 air-sea flux, Pulse-11 biogeochemistry and the SAZ-17 sediment trap mooring. Three profiling floats were deployed: the Argo Hull 638i and Southern Ocean Carbon Cycling Observations and Modeling (SOCCOM) ID8514 and ID9315. The EOV paper documentation - Multibeam (EM122, EM710 and ME70 and SBP120), CTD and XBT logs were scanned, archived and entered in the records management system TRIM, reference "in2015_V01". ELOG files were generated as csv formatted files and archived. The TRIAXUS log book entries have been scanned and archived. All voyage documentation is archived c/o the Data Centre in Hobart available electronically to MNF support via the local network folder "global_docs". Access to voyage documentation for non CSIRO participants can be made via DataLibrariansOAMNF@csiro.au. The archive for the IN2015_V01 EOV data will be held temporarily within the CSIRO Oceans and Atmosphere Data Centre in Hobart, with a permanent archive to be located at the CSIRO Data Access Portal (DAP), providing access to participants and processors of the data collected on the Marine National Facility RV Investigator IN2015_V01.
