Abstract
This resource includes bathymetry data acquired during the Arafura Marine Park bathymetry survey using Kongsberg EM300 multibeam sonar system. The Arafura Marine Park bathymetry survey (SS052005/GA0282); also known as Arafura Sea survey; was led by Geoscience Australia aboard the National facility research vessel Southern Surveyor from the 30th of April to the 27th of May 2005. The primary objective of the expedition was to collect seismic and oceanographic data, mapping the sea floor and taking geological samples over various habitats. Another objective was to collect baseline information on the biodiversity of a smaller region within the Arafura Sea. This V1 dataset contains two 5m and 8m resolution 32-bit floating point geotiff files of the new Arafura Marine Park bathymetry, derived from the processed EM300 bathymetry data, using CARIS HIPS and SIPS software. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

Lineage
This is a V1 product. This dataset was produced using CARIS HIPS/SIPS v.11.3.23 and the AusSeabed-recommended processing methodology as follows. 1. A new Caris project was created in conjuction with existing or newly created vessel configuration file(s). 2. TPU and tide were computed and all data were georeferenced (merged) to the EGM2008 vertical datum. 3. A 5 and 8 metre resolution CUBE was generated as a reference surface for data cleaning. 4. An automated data cleaning was undertaken using a surface cleaning method that utilises the reference surface. 5. Further manual cleaning was conducted as required after visual assessment of the auto-cleaned surface. 6. The final grid was produced at a resolution nearest the banded depth resolution that is based on the auto-resolution estimate provided in Caris. 7. The final processed grids were exported as nine 32-bit floating point Geotiffs at 5 and 8m resolution, referenced to EGM2008.
