Data from the Australian Ocean Data Network describes an incubation experiment studying the re-establishment of vertical bacterial and foraminiferal zonation in intertidal sediments after sieving. The dataset includes counts of living foraminifera, measurements of redox-sensitive pore water elements, and bacterial abundance quantified via phospholipid-derived fatty acids. The experiment tracked changes over a 49-day incubation period.
Use Cases
- Modeling the vertical re-migration of foraminifera based on oxygen availability over a 21-day period.
- Analyzing the long-term change in bacterial distribution and total abundance after artificial sediment disturbance.
- Studying the relationship between macrobenthic activity and the downward flux of electron acceptors like O2, NO3-, Mn(IV), and Fe(III).
- Comparing fatty acid concentration profiles between field sediments and experimental microcosms where macrobenthos was removed.
Strengths
- Includes measurements from a controlled 49-day incubation experiment.
- Quantifies multiple biological and geochemical parameters: foraminiferal counts, bacterial PLFA abundances, and redox-sensitive pore water elements.
- Provides a direct comparison between field conditions and experimental microcosms.
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.
