Casey Station Multibeam Surveys 2013-2015 (GA-4415, GA-0348 - AAD 3326) - High Resolution Bathymetry Grid
This is a compilation of bathymetry surveys GA-4415 and GA-0348. GA-4415 survey was conducted by the Royal Australian Navy (RAN) and the Australian Antarctic Division (AAD) onboard the RAN vessel Wyatt Earp in 2013/2014, while GA-0348 survey was a collaboration between Geoscience Australia (GA) , the Royal Australian Navy and Australian Antarctic Division acquired by the AAD workboat Howard Burton during December 2014 to February 2015. The survey goal was to acquire high resolution bathymetry data to improve our understanding of the seafloor using multibeam sonar. The bathymetry data collection will be supplemented by physical sampling of the seafloor sediments and video recordings of the biological communities living in the seafloor. The survey covers areas that are frequently used by the RSV Aurora Australis. Improving our understanding of the seabed environment in these shallow coastal waters will ultimately lead to a better environmental management of the Australian Antarctic Territory. The data will also help the RAN to develop more accurate navigation charts therefore reducing the risk to maritime operation in the region.
This dataset is not to be used for navigational purposes.

- Statement
-
The Casey Station bathymetry grid was created by compiling two bathymetry surveys. The GA-4415 survey was conducted by the Royal Australian Navy (RAN) and the Australian Antarctic Division (AAD) onboard the RAN vessel Wyatt Earp in the summer of 2013/2014, while GA-0348 survey was a collaboration between Geoscience Australia (GA) , the Royal Australian Navy and Australian Antarctic Division acquired by the AAD workboat Howard Burton during December 2014 to February 2015. The bathymetry data was processed onboard and further processing was conducted in Geoscience Australia by Michele Spinoccia, using CARIS HIPS & SIPS ver 7.1.2. 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 artefacts. 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-49S. 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 artefacts 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 the grid. Velocity corrections were performed to correct for different artefacts and mismatches. One 1m grid resolution was produced for UTM-49S zone. 9. The processed data was finally exported as grids soundings or false coloured images for presentation and reporting and as final processed data in ASCII XYZ as well as geotif formats of 1m resolution. 10-The ASCII grids were then imported into ARC catalogue/info to create a raster file for the UTM zone and one of the entire survey, and a KML file was created to be imported into google earth.
