    Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the entire voyage. During the voyage, there was 2,581 transect counts of seabirds of 61 species. Coverage was good over the area around Heard and McDonald islands, with some coverage also of Gunnari Ridge. Also covered some deeper parts of the Central Kerguelen Plateau. There were 31 sightings of sea mammals away from the immediate vicinity of Heard and McDonald islands (fur seals were sufficiently common in waters around Heard and McDonald Island to be treated using the same method as for seabirds). Sightings included five species of whales and three species of dolphins. The most intriguing series of sightings comprised seven sightings (approximately eight animals) of blue whales over Gunnari Ridge on 9/10 February (another sighting on 21 January may have been in the same area, as it was approximately 1° north and 1° west of the February sightings) The data has been published to the Ocean Biodiversity Information System (OBIS https://obis.org).

  • This record describes Hydrology (HYD) data collected from the Marine National Facility RV Investigator voyage in2016_v01 Titled: "HEOBI: Heard Earth-Ocean-Biosphere Interactions". The voyage took place between the 7th January to 27th February, 2016 departing Freemantle (WA) and returning to Hobart (TAS). Hydrology samples were collected from Niskin bottles sampled at various depths during a Conductivity-Temperature-Depth (CTD) deployment. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium. Samples were also collected every 2 hours for nutrient analysis from the underway system which collects water from a 7 m depth and is not filtered. This dataset has been archived within the CSIRO O&A Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the voyage report and data processing report.

  • This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage in2016_v02, titled "IMOS Southern Ocean Time Series Automated Moorings for Climate and Carbon Cycle Studies Southwest of Tasmania." This voyage took place between the 14th of March, 2016 and the 16th of April, 2016, departing from Hobart (TAS) and returning to Hobart. Hydrology samples were collected from Niskin bottles sampled at various depths during a Conductivity-Temperature-Depth (CTD) deployment. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium.

  • This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V01, titled: 'HEOBI: Heard Earth-Ocean-Biosphere Interactions' which departed Fremantle on the 8th January 2016 and returned to Hobart on the 27th February 2016. Data for 55 deployments were acquired using the Seabird SBE911 CTD unit 20, fitted with 24 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 primary sensor had a standard deviation (S.D) of 0.0013449 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the secondary oxygen and primary temperature and conductivity sensors. The dissolved oxygen data calibration fit had a S.D. of 0.91455uM. The agreement between the CTD and bottle data was good. A dual channel Fluorometer and an oxidation-reduction potential (ORP) sensor were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report. NOTE: The netCDF variable in the binned file has the incorrect instrument data for the fluorometer. In the published data it is as follows: fluorometer:manufacturer = "Chelsea" ; fluorometer:model = "Aquatracka" ; fluorometer:serialNo = "065941001" ; fluorometer:unitNo = 2. ; The data should read: fluorometer:manufacturer = "Wetlabs" ; fluorometer:model = " FLBBRTD" ; fluorometer:serialNo = "3698" ; fluorometer:unitNo = 2. ; The actual data is unaffected.
