Buried Reef Structures in the Lennard Shelf, Canning Basin

Western Australia's Lennard Shelf in the Canning Basin contains evidence of buried Upper Devonian reef structures. Analysis of seismic-record sections from the Meda No. 1 borehole and sixteen other sections identified frequency anomalies indicative of reef presence. The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Identify potential reef structures based on seismic frequency anomalies mentioned in the description
• Model differential compaction of sedimentary layers above buried reefs
• Correlate seismic reflection data with borehole findings like Meda No. 1
• Map the distribution of suspected reef structures within the Lennard Shelf

Strengths

• Analysis includes sixteen selected seismic-record sections, with four showing confirmed anomalies.
• Findings are based on a specific borehole (Meda No. 1) providing ground truth.
• The dataset is hosted by an authoritative organization, the Australian Ocean Data Network.

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 bias inherent to data_gov_au, focusing solely on the Lennard Shelf.
