This record describes data from the The time of flight aerosol chemical speciation monitor (ToF-ACSM) collected on the Marine National Facility RV Investigator Event voyage IN2015_E01. This was a cold-water trial voyage for the RV Investigator departing Hobart on the 29th January and returning to Hobart on the 18th of February, 2015. The ToF-ACSM was performed using instrument Aerodyne ToF-ACSM-009. It makes continuous online measurements of chemical composition and mass of non refractory submicron particles. Non refractory is defined here as any particle that volatilises at 600c. Composition analysis for particulate ammonium, nitrate, sulfate, chloride, and organic species. Separation and quantification of organic aerosol species including hydrocarbon-like organic aerosol(HOA) and oxygenated organic aerosol(OOA) which is linked to secondary aerosol sources(SOA). Calibration was carried out during installation on Ship in the air chemistry lab. Last calibration date: 27 Jan 2015.

This record describes the End of Voyage (EOV) archive from the Marine National Facility RV Investigator trial voyage IN2015_E01 - Cold Water Trial voyage (including Atmospherics). This voyage took place from Hobart to Hobart from the 29th January to 18th February 2015 and went to 65 degrees south. The voyage objectives included testing the cold water and atmospheric operations; the collection and processing of data and samples to test laboratories, facilities and on board systems; specific testing and checks of aerosol sampling mast, aerosol laboratory and air-chemistry laboratory. Geophysical Survey Mapping data collection, including instrument calibrations, testing of equipment and deployments of XBTs. Data Acquisition operations including the integration and test of underway instruments, new atmospheric instruments and drop keel instrumentation. Data collected included Acoustic Doppler Current Profiler (ADCP)(75, 150 KHz), Underway (UWY), Gravity, SST Radiometer, Atmospheric data (Absorption Photometer, Nephelometer, Ozone and Radon), Greenhouse data (Aerodyne and Picarro), Underway pCO2, Echosounders (12, 18, 38, 70, 120, 200, 333, Bridge 200 KHz), Multibeam (EM122, EM710, ME70 and SBP120), Deep Towed Camera (DTC), Baited Remote Underwater Video System (BRUVS) and XBT. Additional Aerosol data collected included TSI 3772 Condensation Particle Counter (CPC), 3787, Time of flight aerosol chemical speciation monitor (ToF-ACSM), Cloud Condensation Nuclei Counter (CCN), Spectronus - trace gas analyser based on Fourier Transform Infrared spectrometry (FTIR), Long Scanning Mobility Particle Size (longSMPS), Nano Scanning Mobility Particle Size (nanoSMPS), Neutral Cluster Air Ion Spectrometer (NAIS), Proton Transfer Reaction Mass Spectrometer (PTR-MS), PTRMS_AUX, Radiosondes_balloons, Sequencer (SEQ) and Volatility Hygroscopicity Tandem Differential Mobility Analyser (VHTDMA). The EOV paper documentation - Multibeam (EM122, EM710, ME70 and SBP120), Gravity Meter and XBT logs are scanned, archived and entered in the records management system TRIM, reference "in2015_e01". ELOG files are 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_E01 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_E01.
