Jervis Bay Biogeochemistry and Infauna Survey Across Seasons

Thirty-two stations were sampled in Jervis Bay to collect paired geochemical and biological data. The survey by the Australian Ocean Data Network was designed to investigate fine-scale variability and seasonal differences by combining results with a previous winter survey. Preliminary results from 2009 indicated most physical variables and infaunal assemblages varied between seasons.

Use Cases

• Modeling relationships between physical variables and infaunal assemblages based on paired geochemical and biological samples.
• Investigating fine-scale spatial variability in marine ecosystems based on replicate samples taken at eight stations.
• Analyzing seasonal changes in coastal biogeochemistry based on data combined from two surveys across different seasons.
• Assessing the trade-off between spatial coverage and replication in marine survey design based on the described methodology.

Strengths

• Survey design includes spatial replication at thirty-two stations and temporal replication across two seasons.
• Fine-scale variability is investigated with three pairs of grabs deployed at eight stations.
• Data collection includes both geochemical samples and infaunal assemblage records.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, being focused solely on Jervis Bay.
