A dataset modelling bio-irrigation rates in sediments of Port Phillip Bay, Australia. The Australian Ocean Data Network produced it from benthic incubation chambers using deuterium and dissolved caesium tracers. Modelling indicates advection depths of 20-50 cm and rates between 150 and 700 mL h-1.
Use Cases
- Modeling pore-water solute transport across the sediment-water interface based on tracer incubation data.
- Analyzing regional consistency of bio-irrigation depth and rate based on chamber deployments at four sites.
- Estimating whole-bay water column turnover through sediments based on lower advection rates.
- Comparing bio-irrigation activity across different bay regions based on sediment type and depth.
- Investigating uncertainty in tracer models due to adsorption onto sediment particles, as mentioned for dissolved caesium.
Strengths
- Data is derived from seven benthic chambers deployed at four distinct sites, providing multiple measurement points.
- Model results provide specific advection depth ranges (20-50 cm) and rate ranges (150-700 mL h-1).
- Chamber deployments within the same region showed consistent results, indicating methodological reliability.
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 2026-05-05 01:29:13.327026.
