Marine Geology Survey of the Arafura Sea, 1969

A 1969 marine geological survey of the northern Australian continental shelf between longitudes 130° and 136°E and latitudes 8° and 12°S, covering an area of about 240,000 km². The survey was carried out by BMR using the vessel San Pedro Sound and the Japanese research submersible Yomiuri. The results are presented as a bulletin, continuing earlier work in the Timor Sea and northwest shelf.

Use Cases

• Map regional seabed composition based on the geological reconnaissance survey.
• Analyze continental shelf structure based on the defined survey area coordinates.
• Study historical marine survey methodologies based on the described use of a research submersible and supply vessel.

Strengths

• Defined survey area of about 240,000 km² with specific longitude and latitude coordinates.
• Survey conducted with specialized equipment, including the research submersible Yomiuri.

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 specific 1969 survey; freshness should be verified for contemporary applications.
