Australian Ocean Data Network hosts data from an incubation experiment studying the re-establishment of vertical bacterial and foraminiferal zonation in intertidal sediments after artificial disturbance. The dataset includes counts of living foraminifera and measurements of redox-sensitive pore water elements using voltammetric microelectrodes, alongside bacterial abundance quantified via phospholipid-derived fatty acid analysis. The experiment tracked recovery over a 49-day period.
Use Cases
- Modeling the recovery timeline of microbial communities after sediment disturbance based on the 49-day incubation period
- Analyzing the relationship between oxygen presence and foraminiferal migration based on the described re-migration to oxygenated layers
- Studying vertical zonation patterns in intertidal sediments based on the depth-resolved measurements of bacterial abundance and fatty acids
- Comparing field and laboratory sediment mixing processes based on the described differences attributed to macrobenthic activity
Strengths
- Includes direct biological counts (Rose Bengal stained foraminifera) and geochemical measurements (redox-sensitive elements via voltammetric microelectrode)
- Describes a controlled 49-day incubation experiment with comparisons to field conditions
- Quantifies bacterial abundance using phospholipid-derived fatty acid (PLFA) analysis for the range C12-C22
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Freshness should be verified; last updated date is 2026-06-23 03:36:25.837032
