Brief description

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2015_V02 titled "Sustained monitoring of the East Australian Current: Mass, heat and freshwater transports". The voyage took place between May 15 and May 26, 2015, departing from Sydney (NSW) and arriving in Brisbane (QLD).

The purpose of this voyage was to undertake swath mapping off of Fraser Island out to the abyssal plain. This was used to assist in defining the location of 6 mooring sites.

This dataset is published with the permission of CSIRO. Not to be used for navigational purposes.

The dataset contains bathymetry grids of 10m to 210m resolution of the East Australian Current, produced from the processed EM122 and EM710 bathymetry data.

Lineage

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 25m using Swath Angle determination. Areas were then further edited using subset editor.

The 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.
