IN2019_E01 Arafura and Coral Sea Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2019_E01 titled "Post-Dry Dock Calibration Trials". The voyage took place between July 19 and August 2, 2019, departing from Singapore and arriving in Cairns (QLD).\n\nThe purpose of this voyage was to conduct post-dry dock equipment calibration and commissioning, sea trials and personnel training.\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 Arafura and Coral Sea produced from the processed EM122 and EM710 bathymetry data.\nLineage: Multibeam data was logged from the EM’s in Kongsberg’s proprietary *.all format and was converted to be processed within CARIS HIPS and SIPS version 10.3.1. Initial data conversion and processing was performed using the GSM python batch utility. 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. The data was then gridded at the highest resolution possible and further inspected for outliers.\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.
