Jervis Bay Seasonal Biogeochemistry and Infauna Survey

Australian Ocean Data Network collected paired geochemical and biological samples from thirty-two stations in Jervis Bay near Darling Rd to investigate seasonal and fine-scale variation. The survey design included replicate samples at eight stations to examine variability at the scale of meters and incorporated data from a previous winter survey for temporal comparison. Data collection occurred in 2009, with preliminary results indicating variation in physical variables and infaunal assemblages between seasons and across spatial scales.

Use Cases

• Analyze correlation between physical variables (e.g., temperature, salinity from CTD profiles) and infaunal assemblage composition across thirty-two stations.
• Model fine-scale spatial variability (meter-scale) using replicate geochemical and biological samples from eight designated stations.
• Compare infaunal assemblage structure and environmental parameters between winter and other seasons by combining data with the previous GA309 survey.
• Investigate the trade-off between spatial coverage and replication in surrogate studies using the station grid and replicate sampling design.

Strengths

• Survey includes thirty-two sampling stations with paired geochemical and biological data.
• Design incorporates temporal replication via linkage to a prior winter survey (GA309).
• Fine-scale variability is addressed with triplicate sample pairs at eight stations.

Limitations

• Sample size is limited to thirty-two primary stations, restricting broad spatial generalization.
• Data is from a single bay system (Jervis Bay), limiting geographic applicability.
• Preliminary results from 2009 indicate the core data may be temporally stale for contemporary analysis.
