Nutrients in Albatross Bay, Gulf of Carpentaria, northern Australia, were examined monthly between August 1991 and April 1992. Levels of nitrate, nitrite, phosphate and silicate were measured, at four sites, at different depths in the water column.

This record describes data from the ATR-FTIR and Raman spectrometers collected on the Marine National Facility RV Investigator voyage IN2015_V01. This was a trial voyage for the RV Investigator departing Hobart on the 21st March and returning to Hobart on the 29th March, 2015. The PerkinElmer Spectrum 2 Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR)Spectrometer (serial # 99683) on loan from PerkinElmer Australia. The instrument acquires infrared spectra of thin samples such as phytoplankton deposits on filters. FTIR spectra: 144 spectra from 48 samples from 6 sites Calibration of the PerkinElmer instrument performed by the company prior to the voyage. The BaySpec Agility Raman spectrometer with 1064 nm excitation laser and fibre probe optics (serial # P1480093) owned by Monash University. The instrument acquires Raman spectra of phytoplankton deposits. Raman spectra: 72 spectra from 12 samples from 2 sites Calibration of the Monash University instrument last performed 26 February 2015.

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.

This record describes the End of Voyage archive from the Marine National Facility (MNF) RV Investigator voyage IN2016_V01, titled: "HEOBI: Heard Earth-Ocean-Biosphere Interactions." The voyage took place from Fremantle (WA) to Hobart (TAS) between January 7 and February 27, 2016. For further information refer to the Voyage documentation links below. Data collected include: Acoustic Doppler Current Profiler (ADCP: 150 KHz and LADCP), CTD and Hydrology, Gravitometer, SST Radiometer, Absorption Photometer, Nephelometer, Ozone, Radon, Greenhouse (Aerodyne and Picarro), and pCO2 sensors, Fisheries Echosounder (EK60), Bridge Echosunder (200 KHz), Multibeam Echosounder (EM122, EM710, ME70 and SBP120), CTD/Hydrology and Expendable Bathythermographs (XBTs). Voyage-specific data include: Trace Metal Rosette (TMR), Triaxus, Ultra-Short Base Line (USBL) positioning system, Video, Scanning Mobility Particle Size (SMPS), Liquid Scintillation counter (Hidex), Laser Optical Particle Counter (LOPC), Disdrometer (rain droplet size), Rock-samples, Aerosol Trace Elements, Biological Samples, Dissolved Trace Elements, Equilibrator Inlet Mass Spectrometer (EIMS), Fluorescence Induction and Relaxation instrument (FIRe), submersible ultra-violet spectrometric nitrate detector (ISUNA), Miniature Autonomous Plume Recorder (MAPR), Microbial activity and diversity, miniaturized water sampler (Minimone), Particulate Trace Elements, Radiogenic isotope analysis samples, Wildlife observations, Deep Towed Camera (DTC) and Argo float deployments. The archive for the IN2016_V01 EOV data is curated by the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart, with a permanent archive located at the CSIRO Data Access Portal (DAP, https://data.csiro.au/dap/), providing access to participants and processors of the data collected in the voyage. All voyage documentation is available electronically to MNF support via the local network. Access to voyage documentation for non-CSIRO participants can be made via DataLibrariansOAMNF@csiro.au.
