Geoscience Australia Marine Survey 282 provides a post-survey report on shallow gas and benthic habitat mapping in the Arafura Sea. The dataset includes geophysical indicators, core analysis confirming microbial gas, and correlations between habitat and biodiversity of benthic fauna. It is hosted by the Australian Ocean Data Network and was last updated in April 2026.
Use Cases
- Mapping pockmark field density (~350/km2) based on geophysical survey data
- Analyzing benthic biodiversity correlations based on substrate hardness mentioned in the description
- Investigating gas migration pathways based on links between deep faults and sea bed observations
- Assessing habitat uniformity based on coverage of low-relief benthos (<5% surface area)
Strengths
- Includes confirmed microbial gas origin from core analysis
- Correlates benthic fauna biodiversity with substrate hardness
- Links pockmark field development (~350/km2) to sediment type and gas sources
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
