North-East Beagle Gulf Bathymetry Survey, 30m Resolution (2021)

A bathymetry survey acquired from 1 May 2021 to 13 Jul 2021 for the Australian Hydrographic Office. Data was collected onboard the MV Offshore Guardian in the North-East Beagle Gulf and Clarence Strait, Northern Territory, using a Kongsberg EM2040 07 MK II sonar. The processed dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seafloor topography and morphology based on high-resolution bathymetry data.
• Analyzing underwater terrain for marine habitat mapping based on the described survey area.
• Supporting coastal and offshore engineering planning with precise depth measurements.
• Creating base maps for oceanographic research using the processed GeoTIFF grid.

Strengths

• Survey conducted over a defined period from 1 May 2021 to 13 Jul 2021.
• Data processed to a specific 30-meter resolution grid.
• Acquired using a named, modern multibeam sonar system (Kongsberg EM2040 07 MK II).
• Explicitly states the dataset is not for navigational purposes, clarifying its intended use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the single survey period and location.
