Landscape Mapping for Antarctic Specially Protected Area 143 Management

Australian Ocean Data Network presents geological mapping and aerial imagery results from Antarctic Specially Protected Area (ASPA) No. 143 Marine Plain. The dataset includes surficial geology mapping of the 400 km2 Vestfold Hills region at a 1:2000 scale and polygons outlining recommended helicopter landing areas. This evidence was presented at the SCAR Open Science Conference 2024 to inform ASPA management decisions.

Use Cases

• Assessing risks from foot traffic and helicopter access based on mapped surficial geology and Sørsdal Formation boundaries.
• Planning future monitoring strategies based on field observations and aerial imagery of Marine Plain.
• Informing permitting decisions for protected areas using evidence from geological mapping and digital elevation models.
• Identifying suitable helicopter landing zones using buffered polygons away from vulnerable formations and lakes.

Strengths

• Mapping covers a 400 km2 ice-free region (Vestfold Hills) at a detailed 1:2000 scale.
• Analysis integrates multiple data sources: aerial photos, satellite imagery, a digital elevation model, and field observations.
• Dataset is directly linked to a specific management challenge for Antarctic Specially Protected Area No. 143.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Vestfold Hills region.
