AHO Reference Surfaces: Bathymetry Survey of Gulf St Vincent, 1m Resolution

A September 2020 bathymetry survey acquired for the Australian Hydrographic Office in Gulf St Vincent, South Australia. The dataset consists of 1m resolution grids for two surveyed sites, processed from multibeam and singlebeam echosounder data. It was created for calibrating multibeam echosounders under the Hydroscheme Industry Partnership Program.

Use Cases

• Calibrating multibeam echosounders based on the high-resolution reference surfaces.
• Analyzing seafloor morphology based on the 1m resolution bathymetric grids.
• Comparing vertical datums (MSL, LAT, Ellipsoid) for the surveyed sites.
• Supporting marine spatial planning based on detailed bathymetry of Gulf St Vincent.

Strengths

• High-resolution 1m grid derived from Kongsberg EM 2040 multibeam and EA440 singlebeam echosounders.
• Provides separate grids in three vertical datums (MSL, LAT, Ellipsoid) for two surveyed sites.
• Data processed using Caris HIPS & SIPS, a standard hydrographic processing suite.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area in Gulf St Vincent.
