Faust Capel Basins Survey (GA-2436/ TAN0713) - Bathymetry grids
The remote Eastern frontiers project aimed to provide a geological and petroleum prospectivity assessement of the Faust Capel Basins. Funded through Australian Governement Initiatives (Energy Security Program). The Faust Capel Basins survey GA-2436/ TAN0713 was acquired by Geoscience Australia onboard the RV Tangaroa (operated by NIWA) from the 6th of October to the 22nd of November 2007. The geographic range stretched from Wellington to the Faust Capel Basins to Lord Howe Island and back to Wellington. Approximately 8,945 sailing km of multibeam bathymetry was acquired. The high resolution bathymetry data imaged seafloor features in unprecedented detail, revealing the effects of recent magmatic activity and fluid migration on the seafloor. It also produced a new image of a flat topped unexplored seamount. A member of the Lord Howe Rise seamount chain.<p><p>This dataset is not to be used for navigational purposes.

The Faust Capel Basins survey, GA-2436 TAN0713 was acquired by Geoscience Australia onboard the RV tangaroa from the 06th of October to the 22nd of November 2007.
The Chief scientist onboard was Dr. Peter Harris and Dr. Andrew Heap.
This dataset was acquired and processed onboard by Cameron Buchanan and Michele Spinoccia and further processing was conducted in the office by Michele Spinoccia, using CARIS HIPS & SIPS ver 7.1.2.
1. First a vessel configuration file was created where the co-ordinates of the motion sensor and DGPS antenna and patch test offsets were recorded.
2. A new project was then created and the vessel configuration file was attached to the project file.
3. The raw swath sonar data, in raw.all format, for each line was then imported into the project and the vessel information assigned to the data.
4. The motion sensor, DGPS and heading data were then cleaned using a filter that averaged adjacent data to remove artifacts.
5. Different sound velocity profiles data for each block were attached to the corresponding raw swath sonar data files to correct the depths for changes in the speed of sound through the water column.
6. Then a new blank field area was defined that specified the geographic area of study and the co-ordinate system used. The co-ordinates for the study areas were WGS84 UTM-60S/ 59S, 58S and 57S.
7. The data was cleaned by applying several filters that removed any remaining spikes in the bathymetry data using user defined threshold values. A visual inspection of the data for each line was then undertaken where artifacts and noisy data not removed by the filtering process were removed manually using Swath and subset editors modules of the Caris HIPS/SIPS software.
8. All the data for each bathymetric, motion sensor, DGPS, heading, tide and sound velocity profile data were merged to produce the final processed data file. A weighted grid of the processed data was then created for each Block.
In GA the tide was applied to the grid to correct for tidal variations and velocity corrections were performed to correct for different artifacts and mismatches.
9. The processed data was finally exported as grids soundings or false colored images for presentation and reporting and as final processed data in ASCII XYZ as well as geotif formats of 20-35-40-50-100m resolution.
10. Using CARIS Base editor 4.0 the grids were exported as ESRI ASCII grid and then imported into ARC catalogue/info to create a raster file for the entire survey.
