Marine Geology Survey of the Arafura Sea, 1969

A marine geological survey of the northern Australian continental shelf conducted by BMR in 1969. The survey covered an area of about 240,000 square kilometers 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 as platforms.

Use Cases

• Map regional seabed composition based on the geological reconnaissance described.
• Analyze continental shelf structure based on the survey's spatial coverage.
• Study historical marine survey methodologies based on the use of the Yomiuri submersible and chartered vessels.

Strengths

• Survey covers a defined area of about 240,000 square kilometers.
• Work is part of a documented regional mapping program, continuing prior studies in the Timor Sea.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a 1969 survey; freshness should be verified for contemporary applications.
