Landscape Mapping for Antarctic Protected Area Management in the Vestfold Hills

Geological mapping and aerial imagery results from Marine Plain, an Antarctic Specially Protected Area (ASPA No. 143). The data, presented at the SCAR Open Science Conference 2024, was produced by researchers citing work from Geoscience Australia. It includes surficial geology mapping of the 400 km² Vestfold Hills region at a 1:2000 scale to inform management decisions regarding foot traffic and helicopter access.

Use Cases

• Identifying recommended helicopter landing zones based on buffers around the vulnerable Sørsdal Formation and lakes.
• Assessing the impact of human access on fragile geological features based on field observations and aerial imagery.
• Monitoring thermokarst features and glacial sediments unique to the ASPA using regional-scale geomorphology mapping.
• Providing evidence-based guidance for ASPA management plans using foundational landform datasets.

Strengths

• Surficial geology mapping covers a 400 km² ice-free region (Vestfold Hills) at a detailed 1:2000 scale.
• Analysis is based on multiple data sources including aerial photos, satellite imagery, a digital elevation model, and field observations.
• Results are directly linked to specific, cited scientific publications and a management plan (ATCM XXXVI 2013).

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Primary file formats are PDF and HTML, which may not be readily machine-readable for analysis.
