Three areas across the Torres Strait-Gulf of Papua shelf form a transect from the Fly River Delta to the Great Barrier Reef shelf edge. The Australian Ocean Data Network provides data on sediments and benthic fossil biota from this shallow platform where shelf depths range from 120 to 140 meters. Despite poor preservation of foraminiferal tests, the species distributions show a strong correlation to environmental variables like water depth, carbonate mud, gravel, and organic carbon flux.
Use Cases
- Model benthic habitat types based on correlations between foraminiferal assemblages and environmental variables like water depth.
- Assess sediment reworking and preservation based on the developed foraminiferal preservation scale and taphonomic features.
- Analyze the influence of factors like percent carbonate mud, percent gravel, and organic carbon flux on microbiotic community distributions.
- Compare the environmental signal strength of benthic foraminifera versus total microbiota for habitat assessment.
Strengths
- Data covers a transect across a shelf from a river delta to a reef shelf edge, providing spatial context.
- Analysis includes multiple environmental attributes: water depth, carbonate mud, gravel, organic carbon flux, temperature, salinity, and grain size.
- Foraminiferal data shows a much stronger correlation to environmental variables than total microbiota, indicating a clear proxy signal.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
