Illuminating the Biodiversity of the Cape Range and Cloates Canyons (FK200308/GA4859)

This resource includes bathymetry data acquired during the Submarine Cape Range Canyons bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems. The Seamounts, Canyons and Reefs of the Coral Sea bathymetry survey was led by Dr. Rachel Przeslawski (Geoscience Australia) with a team of scientists from Geoscience Australia, Curtin University, Western Australian Museum and Scripps Institution of Oceanography aboard the Schmidt Ocean Institute (SOI) RV Falkor from the 8th of March to the 8th of April 2020.


The primary objective of this survey was to map unexplored submarine canyons in the Gascoyne Marine Park. Submarine canyons are crucial habitats for a variety of biota and understanding their geometry, depth and species diversity is underpinned by high resolution bathymetry data. The bathymetry data collected in this survey can assist with scientific research, marine park management and understanding Australia’s marine estate.


This dataset contains a 64m and a 16m, for water depths shallower than 2560m resolution 32-bit geotiff of the Cape Range and Cloates Canyons area produced from the processed EM302 and EM710 bathymetry data combined.


This dataset is not to be used for navigational purposes.

This dataset is published with the permission of the CEO, Geoscience Australia.

Statement

For V1


- Vertical Datum: MSL and Ellipsoid

- Horizontal Datum: WGS84 (epsg-4326)


Processing methodology:

This dataset was produced using CARIS HIPS/SIPS v.11.3.7 and AusSeabed processing methodology as follows:

1. A new Caris project was created in conjunction with existing or newly created vessel configuration file(s).


2. The raw swath sonar data files were imported to the project. GGK is the preferred navigation and ellipsoid height source.


3. The POSMV data files were imported to the project to bring in delayed heave, delayed heave RMS, ellipsoid height and ellipsoid height RMS.


4. TPU and GPS tide were computed and all data were georeferenced (merged) to ellipsoid vertical datum.


5. A CUBE surface was generated as a reference surface for data cleaning.


6. An automated data cleaning using the surface cleaning method with the reference surface was undertaken.


7. The final grid was produced at a single resolution for the entire depth range according to the deepest depth.


8. The second grid was produced by shifting to EGM2008.


9. The final processed grids were exported as a 32-bit floating point Geotiffs at 64m resolution, referenced to ellipsoid and EGM2008.


For V2


- Vertical Datum: EGM2008

- Horizontal Datum: WGS84 (epsg-4326)


Processing methodology (in addition to what was applied in V1):


1. EGM2008 vertical datum was applied to the data.


2. Close inspection and manual filtering of noise


3. Two grids were produced. A 64 m grid and 16 m grid. The 64 m grid includes the whole dataset minus suppressed noise. The 16 m grid only includes depths of 2560 m and shallower to maintain consistent coverage and provides a higher resolution image of the seabed
