Brief description

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2015_E01, titled "Cold Water Trial Voyage (including atmospherics)". The voyage took place between January 29 and February 18, 2015 departing from Hobart (TAS) and arriving in Hobart (TAS).

The purpose of the voyage was to test Investigator equipment to 65° south. EM122 and EM710 were calibrated in transit in Storm Bay and subsequently used to acquire seafloor bathymetry and backscatter information from Hobart to Antarctic waters.

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 Southern Ocean, produced from the processed EM122 and EM710 bathymetry data.

Lineage

Processing was undertaken using Caris HIPS and SIPS 10.3. Swath editing was followed by subset editing.

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.
