Bathymetry of North-East Beagle Gulf and Clarence Strait, Northern Territory (2021)

A 30-meter resolution bathymetric grid of the North-East Beagle Gulf and Clarence Strait, Northern Territory, collected between 1 May 2021 and 13 July 2021. The survey was conducted for the Australian Hydrographic Office by Guardian Geomatics under the Hydroscheme Industry Partnership Program, using a Kongsberg EM2040 07 MK II multibeam echosounder. Data was processed with Caris Hips & Sips software and exported as a 32-bit floating point GeoTIFF.

Use Cases

• Modeling seafloor topography and morphology based on high-resolution bathymetric data.
• Supporting marine habitat mapping and ecological studies based on detailed depth information.
• Informing coastal zone management and planning based on the surveyed area in Northern Territory waters.
• Calibrating and validating regional oceanographic models based on accurate depth measurements.

Strengths

• Data was acquired with a specific, modern multibeam echosounder (Kongsberg EM2040 07 MK II).
• The final product is a georeferenced 30-meter resolution grid.
• Survey has a defined temporal scope from 1 May 2021 to 13 July 2021.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is explicitly not to be used for navigational purposes, limiting its application.
• Row count and total file size are unknown, which may limit suitability assessment.
