IN2015_T02 Sydney to Hobart Transit Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2015_T02, titled "Transit - Sydney to Hobart". The voyage took place between June 22 and June 25, 2015 departing from Sydney (NSW) and arriving in Hobart (TAS).\n\nThis voyage was a three-day transit from Sydney to Hobart, however some opportunistic bathymetric survey was undertaken.\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 Sydney to Hobart, produced from the processed EM122 and EM710 bathymetry data.\nLineage: Data processing for the EM122 and EM710 data was performed using CARIS 8.1.8. Data from both systems were imported into a single CARIS project using different vessel files, Investigator_EM122 and Investigator_EM710. A zero tide file was applied to the data before merging. All lines were swath edited and then gridded at 20 or 30m using Swath Angle determination. Areas were then further edited using subset editor.\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
