  • Australian land and coastline (including Lord Howe Island) at Lowest Astronomical Tide (LAT) datum

    Land features were derived by aggregating and dissolving the boundaries of the 1 degree S57 file (lndare_a layer) series for the Australian continent (+ Lord Howe Island). This represents land the area defined at Lowest Astronomical Tide (LAT) by the Australian Hydrographic Office. The Great Australian Bight was missing from this series, and was replaced by Geoscience Australia's 1:100k coastline. This data has been made available through the data collation process conducted by the NESP Marine Biodiversity Hub Project D3 (Reefs on the Australian Continental Shelf).

    2019-20 Honours project - Characterising upwelling of Circumpolar Deep Water at the Polar Front and investigating submesoscale processes associated with upwelling

    The dataset was collected on the research voyage (IN2018_V05 on RV Investigator) and from satellite observations. The dataset includes in-situ data and satellite data collected at the Polar Front (PF) south of Tasmania in a region where the Antarctic Circumpolar Current (ACC) has a permanent meander upstream of the Macquarie Ridge. This study characterises the upwelling of Circumpolar Deep Water (CDW) in a standing meander of the ACC in the PF south of Tasmania and investigates the submesoscale processes associated with upwelling.
