Brief description

This layer group describes multibeam echosounder data collected on RV Investigator voyage IN2016_T02 titled "Transit – Hobart to Sydney". The voyage took place between August 25 and August 29, 2016, departing from Hobart (TAS) and arriving in Sydney (NSW).

The purpose of this voyage was to move the RV Investigator from Hobart to Syndey prior to IN2016_V04. Additionally, 24 hours was allocated by the MNF to acquire data over two areas known as Minnie Carmichael Rock which is included in this dataset.

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 Hobart to Sydney transit produced from the processed EM122 and EM710 bathymetry data.

Lineage

Multibeam data was logged from the EMs in Kongsberg’s proprietary *.all format and was converted to be processed 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.

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.
