Bremer, Leeuwin and Perth Canyons bathymetry survey (FK200126/GA4865)
This resource includes bathymetry data acquired during the Bremer, Leeuwin and Perth Canyons bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems. The Bremer, Leeuwin and Perth Canyons survey (FK200126/GA4865), also known as The Great Australian Deep-Sea Coral and Canyon Adventure survey ( https://schmidtocean.org/cruise/coralandcanyonadventure), was led by Dr. Julie Trotter (The University of Western Australia) and Dr. Paolo Montagna (Institute of Polar Sciences) aboard the Schmidt Ocean Institute's research vessel Falkor, from the 26th of January to the 25th of February 2020. The primary objective of the expedition was to map underwater landscapes in the Bremer, Leeuwin and Perth Canyons, characterise chemical and physical oceanography, and use the SOIs ROV SuBastian to capture high-definition video and collect samples. This V1 dataset contains nine 2m to 64m resolution 32-bit floating point geotiff files of the bathymetry in these three study areas and transits, derived from the processed EM302 and EM710 bathymetry data, using CARIS HIPS and SIPS software. An independently processed dataset in GSF format is available at https://www.marine-geo.org/tools/search/DataSets.php?data_set_uids=30215,30216 produced by researchers on the cruise: F. Foglini, A. Remia, J. Trotter and P. Montagna (2021; http://get.iedadata.org/doi/330215 & http://get.iedadata.org/doi/330215).
This dataset is not to be used for navigational purposes.

- Statement

While Geoscience Australia (GA) aims to publish data based on the requirements stated in the AusSeabed multibeam guidelines (version 1, https://australian-multibeam-guidelines.github.io), GA will also publish interim products (version 0) that are currently available, but have not yet been standardised (version 1). Users should be aware that V1 products will always supersede V0 products. This dataset was produced using CARIS HIPS/SIPS v.11.3.19 and the AusSeabed-recommended processing methodology as follows.
<p>1. A new Caris project was created in conjunction with existing or newly created vessel configuration file(s).
<p>2. The raw swath sonar data files were imported to the project. GGK is preferred navigation and ellipsoid height sources.
<p>3. The POSMV data files were imported to the project to bring in delayed heave, delayed heave RMS, ellipsoid height and ellipsoid height RMS.
<p>4. TPU and GPS tide were computed and all data were georeferenced (merged) to EGM2008 vertical datum.
<p>5. An auto-resolution CUBE was generated as a reference surface for data cleaning.
<p>6. An automated data cleaning using surface cleaning method with the reference surface was undertaken.
<p>7. Further manual cleaning was conducted as required after visual assessment.
<p>8. The final grid was produced at a resolution nearest the banded depth resolution based on the auto-resolution estimate provided in Caris.
<p>9. The final processed grids were exported as nine 32-bit floating point Geotiffs at 2m to 64m resolution referenced to EGM2008.
