Prydz Bay Sediment and Bathymetry Maps from Antarctic Expeditions

Australian Ocean Data Network hosts a dataset compiling surficial sediment, bathymetric, and geomorphological maps for the Prydz Bay region in East Antarctica. The underlying data includes about 30,000 kilometers of bathymetric data, 6,000 kilometers of sidescan sonar data, and over 250 sediment grab and core samples collected by Japanese, Australian, and Russian expeditions over 15 years. The dataset was last updated on 2026-06-05.

Use Cases

• Map seafloor geomorphic provinces based on compiled bathymetric and sidescan sonar data.
• Analyze surficial sediment distribution patterns using the collection of grab and core samples.
• Study the relationship between lithofacies and underwater topography in the Prydz Bay region.

Strengths

• Compiles data from about 30,000 kilometers of bathymetric surveys.
• Includes over 250 physical sediment samples (grab and core).
• Integrates data from multiple international expeditions (Japanese, Australian, Russian).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats beyond HTML are unknown, which may limit suitability assessment.
