Marine Geological Survey of the Arafura Sea Continental Shelf

Geoscience Australia's Bulletin details a 1969 marine geological survey of the northern Australian continental shelf, covering an area of approximately 240,000 square kilometers. The survey was conducted using the research submersible Yomiuri and the vessel San Pedro Sound from September to December 1969.

Use Cases

• Analyze geological reconnaissance mapping data for the Arafura Sea region to understand continental shelf composition.
• Study survey results from the Yomiuri submersible and San Pedro Sound platform for marine sediment and rock formation patterns.
• Compare this 1969 survey data with prior work in the Timor Sea and northwest shelf for regional geological continuity.

Strengths

• Covers a specific 240,000 square kilometer area of the Australian continental shelf.
• Documents a detailed marine survey conducted over a multi-month period in 1969.
• Represents a continuation of established regional geological mapping programs.

Limitations

• Data is presented in legacy HTML and PDF formats, not machine-readable tabular data.
• The dataset is a historical document from 1969, lacking modern measurements or updates.
• Sample data and specific columnar features are unavailable for direct computational analysis.
