Geophysical indicators and core analysis confirm microbial shallow gas and deeper migrating gas sources in the Arafura Sea. The survey recorded intense pockmark fields at densities of approximately 350 per square kilometer and identified correlations between benthic biodiversity and substrate hardness. This dataset was published by the Australian Ocean Data Network and last updated in June 2026.
Use Cases
- Map shallow gas distribution based on geophysical indicators and core analysis mentioned in the description
- Analyze pockmark field development and density in relation to sediment type and gas sources described in the report
- Model links between deep Proterozoic faults and sea bed features using correlated sub-bottom and seismic data
- Assess benthic habitat quality by correlating biodiversity and abundance with substrate hardness as described
Strengths
- Gas presence confirmed by direct analysis of core material obtained during the survey
- Pockmark field density quantified at approximately 350 per square kilometer
- Correlations established between deep geological faults and sea bed features using multiple data types
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 Arafura Sea
