Marine Geology Survey of the Arafura Sea, 1969

Geoscience Australia Data presents a marine geological survey of the northern Australian continental shelf. The survey was conducted by BMR in 1969, covering an area of about 240,000 km² between longitudes 130° and 136°E and latitudes 8° and 12°S. The work used the research submersible Yomiuri and the vessel San Pedro Sound.

Use Cases

• Analyze seabed composition and structure based on the marine geological survey results.
• Study regional geological reconnaissance mapping of the Arafura Sea continental shelf.
• Investigate the continuation of geological work from the Timor Sea and northwest shelf.
• Examine data collected via submersible and vessel-based platforms in 1969.

Strengths

• Covers a defined area of about 240,000 km².
• Survey conducted over a specific period from 2 May to 6 December 1969.
• Results are part of a program of regional geological reconnaissance mapping.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to a 1969 survey.
