350 pockmarks per square kilometer were mapped in the Arafura Sea, indicating shallow gas migration. The survey confirmed microbial gas origins in Holocene mud-filled channels and correlated benthic biodiversity with substrate hardness. Data was collected by Geoscience Australia and published via the Australian Ocean Data Network.
Use Cases
- Model shallow gas migration pathways based on links between deep Proterozoic faults and sea bed pockmarks
- Map benthic habitat types based on correlations between fauna biodiversity and substrate hardness
- Analyze pockmark field density based on relationships with sea bed sediment type and microbial gas production
Strengths
- Description provides specific density metrics, such as ~350 pockmarks/km2
- Description details confirmed gas origins (microbial) and migration pathways from deeper sedimentary sections
- Description correlates specific benthic fauna (sea whips, fans, soft corals) with substrate types
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data formats are PDF and HTML, which may require extraction for quantitative analysis
