Intertidal Sediment Disturbance: Bacterial and Foraminiferal Response Over 49 Days

Experimental data from incubation studies on intertidal sediments measures the re-establishment of bacterial and foraminiferal communities after artificial disturbance. The dataset includes counts of living foraminifera and measurements of redox-sensitive pore water elements using voltammetric microelectrodes, alongside bacterial abundances quantified via phospholipid-derived fatty acids. It was published by Geoscience Australia Data and last updated on 2026-03 25.

Use Cases

• Modeling the vertical migration of foraminifera based on oxygen presence over a 21-day period.
• Analyzing changes in bacterial abundance and fatty acid concentration profiles with sediment depth.
• Investigating the role of macrobenthic activity in sediment mixing and electron acceptor flux.
• Comparing field and microcosm conditions for bacterial population differentiation using PLFA data.

Strengths

• Data includes specific temporal measurements over a 49-day incubation period.
• Methodology details are provided, including Rose Bengal staining for foraminifera and voltammetric microelectrode use.
• Compares field conditions with controlled microcosm experiments, highlighting ecological drivers.

Limitations

• Row count and column-level documentation are unknown, requiring inference after download.
• The dataset's scale and completeness are not specified in the provided metadata.
