A dataset models bio-irrigation rates in marine sediments using deuterium and caesium tracer experiments from benthic incubation chambers. The study involved seven chambers deployed at four sites in Port Phillip Bay, indicating advection depths of 20-50 cm and rates between 150 and 700 mL h-1. It was published by the Australian Ocean Data Network and last updated in June 2026.
Use Cases
- Modeling pore-water solute transport based on tracer incubation time series
- Comparing bio-irrigation rates across different regions of a bay based on sediment type and depth
- Estimating whole-water-column turnover through sediments based on advection rates
- Assessing the distribution and activity of infauna based on irrigation rate consistency
Strengths
- Data is derived from seven incubation chambers across four distinct sites, providing spatial replication
- Modeling provides specific quantitative ranges for irrigation depth (20-50 cm) and rate (150-700 mL h-1)
- Results show consistency within regions, suggesting reliable local measurements
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- The description notes increased uncertainty for caesium tracer results due to adsorption onto sediment particles
