Disturbance of Intertidal Sediments: The Response of Bacteria and Foraminifera

Geoscience Australia Data provides results from incubation experiments studying the re-establishment of vertical bacterial and foraminiferal zonation in intertidal sediments after sieving. The dataset includes counts of living foraminifera and measurements of redox-sensitive pore water elements, with observations spanning a 49-day incubation period. Data was last updated on 2026-04-20.

Use Cases

• Modeling foraminiferal migration patterns based on oxygen presence and the 21-day re-migration timeframe mentioned in the description
• Analyzing changes in bacterial abundance and fatty acid concentration profiles in disturbed versus field sediments over a 49-day period
• Studying the role of macrobenthic activity in sediment mixing and electron acceptor flux based on the comparison between field and microcosm conditions

Strengths

• Includes specific temporal measurements over a defined 49-day incubation period
• Contains data on multiple biological and geochemical parameters: foraminiferal counts, bacterial abundances via PLFA, and pore water redox elements

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
