Jervis Bay Biogeochemistry and Infauna Seasonal Survey

Environmental and infaunal data were collected from thirty-two stations in Jervis Bay, Australia, across multiple seasons. The survey design included replicate sampling at eight stations to investigate fine-scale variability and incorporated vertical water column profiles. Data collection was conducted by the Australian Ocean Data Network, with samples expected to be processed by late 2009.

Use Cases

• Analyze variation in infaunal assemblages between seasons using paired biological and geochemical samples.
• Investigate fine-scale spatial variability (meter-scale) by comparing replicate grabs from the eight designated stations.
• Model relationships between physical variables (e.g., temperature, salinity from CTD profiles) and biological diversity across the thirty-two station grid.
• Compare station-level variability (hundreds of meters) against within-station replicate variability (meters) for infaunal communities.

Strengths

• Survey includes thirty-two stations with paired geochemical and biological samples.
• Design incorporates temporal replication by combining data with a previous winter survey (GA309).
• Fine-scale spatial analysis enabled by three pairs of replicate grabs at eight stations.
• Vertical environmental profiles provided by CTD casts at grid stations and throughout the bay.

Limitations

• Exact sample size (row count) and specific column variables are not provided.
• Data is from a specific time period (circa 2009), limiting analysis of current conditions.
• Geographic scope is limited to Jervis Bay, Australia, near Darling Rd.
