Prydz Bay Sediment and Bathymetry Maps from Antarctic Expeditions

Over 15 years, Japanese, Australian, and Russian expeditions collected data used to compile surficial sediment, bathymetric, and geomorphological maps of the Prydz Bay region in East Antarctica. The underlying data includes approximately 30,000 kilometers of bathymetric data, 6,000 kilometers of sidescan sonar data, and more than 250 sediment grab and core samples. The dataset is provided by Geoscience Australia Data and was last updated in April 2026.

Use Cases

• Map seafloor geomorphic provinces based on bathymetric and sidescan sonar data.
• Analyze surficial sediment distribution patterns from grab and core samples.
• Model the relationship between lithofacies and underwater topography in a polar bay.

Strengths

• Integrates data from approximately 30,000 kilometers of bathymetric surveys.
• Includes a substantial collection of over 250 physical sediment samples.
• Combines multiple data types (bathymetry, sonar, sediment) for a multi-faceted analysis.

Limitations

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