Marine Geology Survey of the Arafura Sea, 1969

BMR Bulletin presents results from a marine geological survey conducted in the Arafura Sea in 1969. The survey covered approximately 240,000 km² of the northern Australian continental shelf between 130° and 136°E and 8° and 12°S. Work was performed using vessels including the Yomiuri submersible and the San Pedro Sound.

Use Cases

• Map regional geological features based on survey data from the Arafura Sea.
• Analyze sediment composition and structure from samples collected during the 1969 reconnaissance.
• Study the continuity of geological formations between the Timor Sea and northwest shelf regions.
• Model continental shelf morphology based on the described survey area and coordinates.

Strengths

• Survey covers a defined area of approximately 240,000 km².
• Provides a continuation of prior geological work in the Timor Sea and northwest shelf.
• Describes specific vessels and a clear operational timeframe from May to December 1969.

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 geographic and temporal bias inherent to the 1969 survey.
