Marine Geology Survey of the Arafura Sea, 1969

A marine geological survey conducted by BMR in the Arafura Sea during 1969. The survey covers an area of about 240,000 square kilometers on the northern Australian continental shelf between longitudes 130° and 136°E and latitudes 8° and 12°S. Data collection utilized the Japanese research submersible Yomiuri and the chartered vessel San Pedro Sound.

Use Cases

• Map regional seabed composition based on the marine geological survey.
• Analyze continental shelf structure using the defined survey area coordinates.
• Study geological reconnaissance methods from the described 1969 survey campaign.

Strengths

• Survey covers a defined area of about 240,000 square kilometers.
• Provides specific temporal context with survey dates from May to December 1969.
• Describes specific research vessels and equipment used for data collection.

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 the 1969 survey period.
