Ashmore Reef Marine Park Bathymetry Survey (GA4870/FK210409)
This resource includes bathymetry data acquired during the Ashmore Reef Marine Park survey using Kongsberg EM302 and EM710 multibeam sonar systems.
The Ashmore Reef Marine Park bathymetry survey (GA4870/FK210409), also known as the Australian Mesophotic Coral Examination survey, was led by AIMS aboard the Schmidt Ocean Institute's research vessel Falkor, from the 09th of April to the 26th of April 2021.
The primary objective of the expedition was to map Mesophotic Coral Ecosystems (MCE’s), monitor anthropogenic and natural stressors to MCE’s and use an ROV and AUV to capture high definition video and collect samples. The data collected from the expedition will develop baseline knowledge to inform conservation efforts and improve management of the Ashmore Reef Marine Park.
This V1 dataset contains one 16m resolution 32-bit floating point geotiff file of the Ashmore Reef Marine Park 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.

The Ashmore Reef Marine Park Bathymetry Survey was acquired by AIMS onboard the Schmidt Ocean Institute's RV Falkor from the 09th of April to the 26th of April 2021.
The Chief scientist onboard was Dr. Karen Miller (AIMS).
<br>This dataset was acquired and processed onboard by the Falkor team and further processing was conducted in the office by Christopher Yule, using CARIS HIPS & SIPS ver 11.3.16.
<p>Metadata:
<br>The multibeam bathymetry was acquired by the following survey:
<br>- Survey Name: Ashmore Reef Marine Park Bathymetry Survey (GA4870/FK210409)
<br>- Vessel Name: RV Falkor
<br>- Institution: AIMS
<br>- Country: Australia
<br>- Operator: Schmidt Ocean Institute (SOI)
<br>- Multibeam system: Kongsberg EM302 and EM710
<br>- Year of installation: 2011/12
<br>- Nominal sonar frequency: 30kHz/70-100 kHz
<br>- Number of heads: 1 for each
<br>- Number of beams/head: 432 soundings (EM302) and 400 soundings (EM710)
<br>- Beamwidth along track: 1 degree (EM302) & 0.5 degree (EM710)
<br>- Beamwidth across track: 1 degree for both systems
<br>- Pulse length: variable
<br>- Selectable depth range: variable
<br>- Vessel speed: 5 - 7 knots
<br>- Start Date: 09/04/2021
<br>- End Date: 26/04/2021
<br>- Start Port: Darwin
<br>- End Port: Darwin
<br>- Grid resolution: 16 m
<br>- Number of grids: 1
<br>- Use Limitation: This dataset is not to be used for navigational purposes.
<br>- This dataset is published with the permission of the CEO, Geoscience Australia
<br>- Vertical Datum: EGM2008 (~MSL)
<br>- Horizontal Datum: WGS84 (EPSG:4326)
<p>Processing methodology:
<br>This dataset was produced using CARIS HIPS/SIPS v.11.3.16 and AusSeabed processing methodology as follows.
<br>1. A new Caris project was created in conjuction with existing or newly created vessel configuration file(s).
<br>2. The raw swath sonar data files were imported to the project. GGK is preferred navigation and ellipsoid height sources.
<br>3. The posmv data files were imported to the project to bring in delayed heave, delayed heave RMS, ellipsoid height and ellipsoid height RMS.
<br>4. TPU and GPS tide were computed and all data were georeferenced (merged) to EGM2008 vertical datum.
<br>5. An auto-resolution CUBE was generated as a reference surface for data cleaning.
<br>6. An automated data cleaning using surface cleaning method with the reference surface was undertaken.
<br>7. Further manual cleaning was conducted as required after visual assessment.
<br>8. The final grids were produced according to their resolution rounded to the nearest AusSeabed banded depth resolution after the auto-resolution estimate Caris provided.
<br>9. The final processed grid was exported as a 32 bit floating point Geotif at 16m resolution referenced to egm2008.
