Marine Plain Antarctic Protected Area Geological Mapping

Geological mapping and aerial imagery analysis inform management of Antarctic Specially Protected Area No. 143 (Marine Plain). The work includes surficial geology mapping of the 400 km² Vestfold Hills region at a 1:2000 scale. It was presented at the SCAR Open Science Conference in 2024 and is associated with Geoscience Australia.

Use Cases

• Delineate helicopter landing zones by applying buffers around the Sørsdal Formation and lakes using polygon data.
• Assess vulnerability of glacial sediments by comparing mapped landforms in Marine Plain to regional Vestfold Hills geology.
• Monitor impacts of foot traffic by analyzing field observation data against mapped geomorphology and thermokarst features.
• Support management plan revisions with evidence from aerial photo and satellite imagery analysis of bedrock slopes and marine inundation limits.

Strengths

• Surficial geology mapping covers a 400 km² ice-free region.
• Mapping was conducted at a detailed 1:2000 scale.

Limitations

• Sample size and specific row/record counts for observations are unknown.
• Data is presented in PDF and HTML formats, limiting direct machine analysis.
• The temporal coverage of the field observations and imagery is not specified.
