Marine Geology Survey of the Arafura Sea, 1969

A marine geological survey report from the Australian continental shelf in the Arafura Sea. 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 III°S. The work used vessels including the research submersible Yomiuri and the chartered vessel San Pedro Sound.

Use Cases

• Regional geological mapping based on the survey's reconnaissance program.
• Analysis of seabed composition and structure based on the marine geological survey results.
• Historical study of geological exploration techniques based on the use of the Yomiuri submersible and other vessels.

Strengths

• Covers a defined area of about 240,000 km² on the northern Australian continental shelf.
• Documents a specific survey period from 2 May to 6 December 1969.
• Part of a documented program of regional reconnaissance mapping, continuing prior work in the Timor Sea.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias inherent to a survey conducted in 1969.
