Marine Survey Data on Shallow Gas and Benthic Habitats in the Arafura Sea

Geoscience Australia's Marine Survey 282 report presents findings on shallow gas and benthic habitats in the Arafura Sea. The data includes geophysical indicators, core sample analysis confirming microbial gas, and detailed seabed mapping correlating biodiversity with substrate types. The report was last updated on 2026-03-25.

Use Cases

• Mapping pockmark field density and distribution based on geophysical survey data.
• Analyzing correlations between benthic biodiversity and seabed substrate hardness mentioned in the description.
• Investigating links between deep-seated faults and shallow gas migration pathways inferred from seismic data.
• Modeling microbial gas production in Holocene mud-filled channels based on core sample analysis.

Strengths

• Includes confirmed shallow gas presence through core sample analysis.
• Correlates geophysical data with conventional seismic data to identify fault linkages.
• Provides specific density observations for pockmark fields (~350/km2).
• Documents detailed seabed mapping showing biodiversity correlations with substrate type.

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 the Arafura Sea survey area.
