IN2016_V04 Eastern Australia Bathymetry 10m - 210m Multi-resolution AusSeabed products

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2016_V04 titled "Influence of temperature and nutrient supply on the biogeochemical function and diversity of ocean microbes". The voyage took place between August 31 and September 22, 2016, departing from Sydney (NSW) and arriving in Brisbane (QLD).\n\nThe purpose of this voyage was to to resolve how changes in seawater temperature and nutrient concentrations, linked to shifting oceanographic circulation in eastern Australia, influences the diversity of microbial communities and the key biogeochemical transformations (C, N, P, Si, Fe and S) they mediate.\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 Eastern Australia 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 for post processing within Caris HIPS and SIPS version 9.1.2. 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.
