Incubation experiments tracked the re-establishment of bacterial and foraminiferal zonation in sieved intertidal sediments over 49 days. Foraminifera re-migrated to the top 3 mm of oxygenated sediment within 21 days, while total bacterial abundance did not recover to original levels. The Australian Ocean Data Network published this dataset on data.gov.au.
Use Cases
- Modeling oxygen-dependent organism migration based on foraminiferal response to oxygen presence.
- Analyzing long-term changes in bacterial vertical distribution after artificial disturbance.
- Studying the impact of macrobenthic activity on pore water chemistry based on redox-sensitive element measurements.
- Comparing fatty acid concentration profiles between field sediments and experimental microcosms.
Strengths
- Experimental design includes a 49-day incubation period, providing a temporal series.
- Description details specific measurement techniques: Rose Bengal staining for foraminifera and voltammetric microelectrodes for pore water.
- Analysis includes phospholipid-derived fatty acids (PLFA) methyl esters for bacterial quantification.
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 metadata update was 2026-04-16.
