Arafura Marine Park survey (SOL7491/GA0366)
This resource includes bathymetry data for Arafura Marine Park (Arafura Sea) collected by Geoscience Australia (GA) and the Australian Institute of Marine Science during the period 2 – 15 November 2020 on the RV Solander. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and AIMS. The purpose of the project was to build baseline information for benthic habitats in Arafura Marine Park that will support ongoing environmental monitoring within the North Marine Park Network as part of the 10-year management plan (2018-2028). Data acquisition for the project included multibeam bathymetry and backscatter for two areas (Money Shoal and Pillar Bank), seabed samples and underwater imagery of benthic communities and demersal fish. This bathymetry dataset contains a 6 m resolution 32-bit geotiff of the survey areas produced from the processed EM2040C Dual Head system using CARIS HIPS and SIPS software. A detailed report on the survey is provided in: Picard, K. Stowar, M., Roberts, N., Siwabessy, J., Abdul Wahab, M.A., Galaiduk, R., Miller, K., Nichol, S. 2021. Arafura Marine Park Post Survey Report. Report to the National Environmental Science Program, Marine Biodiversity Hub.

This is a V1 product for SOL7491/GA-0366.
The Chief scientist onboard was Ms Kim Picard & Mr Marcus Stowar.
This dataset was produced using CARIS HIPS/SIPS version 11.3.12
For any metadata questions, please download the Metadata.txt file located with the dataset.
Processing methodology:
Following the CARIS HIPS/SIPS workflow,
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 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 data were attached to the corresponding raw swath sonar data files.
6. A new blank surface 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 a 32 bit Geotif format at 6 m resolution referenced to EGM2008 (~ to mean sea level).
