Raine Island bathymetry survey (FK210321/GA4873)
This resource includes bathymetry data acquired during the Raine Island bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems.
The Raine Island bathymetry survey (FK210321/GA4873); also known as Brisbane to Darwin transit survey; was led by James Cook University aboard the Schmidt Ocean Institute's research vessel Falkor from the 21st of March to the 4th of April 2021.
The primary objective of the expedition was to transit from Brisbane to Darwin.
Another objective was to map underwater landscapes in the north of the Coral Sea around Raine Island and the Pandora Entrance.
This V1 dataset contains twelve 2m to 64m resolution 32-bit floating point geotiff files of the new Raine Island bathymetry, derived from the processed EM302 and EM710 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.

While AusSeabed aims to publish data to the level of adherence based on the requirements stated in the AusSeabed multibeam guidelines (version 1), we 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 is a V1 product. This dataset was produced using CARIS HIPS/SIPS v.11.3.19
1. A vessel configuration file was created where the co-ordinates of the motion sensor, DGPS antenna and patch test offsets were recorded.
2. A new project was created and the vessel configuration file attached to the project file.
3. The raw swath sonar data files, in raw.all format, for each line was imported into the project and the vessel information assigned to the data.EGM2008 model/vertical reference system is our first preference and when not available or possible to do so, a tidal zone data is the next preference to be applied to the data
4. The motion sensor, DGPS and heading data were cleaned using a filter that averaged adjacent data to remove artefacts.
5. Sound velocity profiles data for each block of the data were attached to the corresponding raw swath sonar data files.
6. A new blank fieldsheet area was defined that specified the geographic area of study and the co-ordinate system used.
7. The data was cleaned by applying several filters that removed any spikes in the data using user defined threshold values.
8. Data were inspected visually for each line where artifacts and noisy data had not removed by the filtering process.
9. Remaining spikes were removed manually using the swath and subset editor modules.
10. All the data, i.e. bathymetric sounding and ancillary data, were merged to produce the final processed data file
11. A weighted grid of the processed data was then created.
12. Independent velocity corrections were performed where velocity artefacts were observed.
13. The final processed grid was exported as atwelve 32 bit floating point Geotif format at 2m to 64 m resolution referenced to egm2008.
