Abstract

The Approaches to Darwin, Beagle Gulf bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the M/V Limitless and PHS Zephyr during the period 26 June – 30 August 2020. This was a contracted survey conducted as part of the HydroScheme Industry Partnership Program (HIPP). The survey area lies North-West of Cox Peninsula, encompassing South Gutter and is bounded by North Gutter, Fenton Patches and Fish Reef. Bathymetry data was acquired using a Kongsberg R2Sonic 2026 and R2Sonic 2024 and processed using QPS Qimera V2.0.1. The dataset was then exported to GeoTIFF using CARIS HIPS and SIPS software. This dataset contains a 30m-resolution 32-bit floating point GeoTIFF file. This dataset is not to be used for navigation.

Processed in accordance with HIPP SOR 2020v 1.2 using CUBE techniques, 1m and 2m CUBE surfaces generated as the final L3 product (a gridded surface derived from cleaned point data). 2. Data was provided to Geoscience Australia for publication. 3. The final processed grid was exported as a 32-bit floating point Geotiff at 30 m resolution, referenced to MSL, WGS 84 (EPSG:4326). DATA QUALITY This dataset has been subject to independent post-production validation and testing. Tests have been performed for data completeness, correct spatial representation, attribute accuracy, logical consistency, metadata completeness and correctness, and where appropriate for compliance with Geoscience Australia's data dictionaries. Errors found in this dataset should be reported to: Corporate Data Manager Geoscience Australia GPO Box 378 Canberra ACT 2601, Australia Email: Sales@ga.gov.au Reported Errors will be rectified in subsequent data releases, if any.
