Marine Geology of the Arafura Sea, 1969 Survey

A 1969 marine geological survey of the northern Australian continental shelf conducted by BMR. The survey covered an area of about 240,000 km² between longitudes 130° and 136°E and latitudes 8° and 12°S, using vessels including the research submersible Yomiuri. The results are presented in a bulletin from Geoscience Australia.

Use Cases

• Map regional seabed composition based on the geological survey results.
• Analyze continental shelf structure based on the described survey area and coordinates.
• Study historical marine geological reconnaissance methods based on the 1969 survey campaign details.

Strengths

• Survey covers a defined area of about 240,000 km².
• Specific temporal coverage from the 1969 survey campaign is documented.
