The CSIRO Bayside Air Quality Station datasets contain measurements of important urban air pollutants for the period of June 2004 to the present day measured in the atmosphere at the CSIRO Aspendale measuring station. There are variables for both chemical (gases such as carbon monoxide(CO), nitrogen oxides (NO, NO2, NOx), sulfur dioxide(SO2) & ozone(O3)) and physical properties (particulate mass measurements: size<10µm(Pm10), size<2.5µm(Pm2.5), size<100nm(UFP)). Variable data is logged on a minutely basis and is available in daily-average annual and hourly-average monthly excel spreadsheet formats. The Bayside Air Quality Station is located at CSIRO Marine and Atmospheric Research (CMAR) Aspendale, Victoria (38° 01' 41" South, 145° 01' 48" East)
This record describes nitrate concentration data obtained with the Seabird/Satlantic Submersible Ultraviolet Nitrate Analyser (SUNA) owned by ACE CRC (Tom Trull), collected on the Marine National Facility RV Investigator voyage IN2015_V01, departing Hobart on the 21st March and returning to Hobart on the 29th of March, 2015. The SUNA V2 determines nitrate concentrations from ultra-violet spectra. It was deployed on the Triaxus towed body. Calibration onboard IN2015_v01 against Milli-Q purified water blank and Hydrochemistry 7 uM nitrate standard in seawater.
