IN2018_T01 Hobart to Brisbane Transit Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2018_T01 titled "Physical, chemical and biogeochemical gradients in the East Australian Current". The voyage took place between April 5 and April 14, 2018, departing from Hobart (TAS) and arriving in Brisbane (QLD).\n\nThe purpose of this voyage was to transport the ship from Hobart to Brisbane, as well as to introduce UTAS students to research at sea and standard methods in physical, chemical and biological oceanography.\n\nThis dataset is published with the permission of CSIRO. Not to be used for navigational purposes.\n\nThe dataset contains bathymetry grids of 10m to 210m resolution of the transit from Hobart to Brisbane produced from the processed EM122 and EM710 bathymetry data.\n\nLineage: Multibeam data was logged from the EMs in Kongsberg’s proprietary *.all format and was converted to be processed within Caris HIPS and SIPS version 10.3.3. Once the raw files were converted into the HIPS and SIPS format the data was analysed for noise. Zerotide was applied, and the lines were merged using the vessel file appropriate for either the EM122 or EM710. \n\nThe data was then gridded at multiple resolutions in python Caris batch script using a Depth filter Vs Resolution guideline derived from AusSeabed Multibeam guidelines v2 and further inspected for outliers. Final raster products are available in L3 folder of this collection. Final processed data were also exported per line as GSF and ASCII format and available in the L2 folder of this collection.\n
