Temporal and fine-scale variation in the biogeochemistry of Jervis Bay

A 2009 survey collected paired geochemical and biological samples from thirty-two stations in Jervis Bay, Australia, to investigate seasonal and fine-scale variation. The data, managed by the Australian Ocean Data Network, includes environmental and infaunal samples from a defined grid near Darling Rd, with CTD profiles for vertical temperature and salinity. Preliminary results indicated variation in physical variables and infaunal assemblages between seasons and across spatial scales.

Use Cases

• Modeling relationships between physical variables and infaunal assemblages based on paired geochemical and biological samples.
• Investigating fine-scale spatial variability (meter-scale) based on replicate grab samples taken at eight stations.
• Analyzing seasonal variation in marine biogeochemistry by combining this survey with a previous winter survey (GA309).
• Studying vertical water column profiles based on CTD-derived temperature and salinity data.

Strengths

• Survey design includes spatial and temporal replication with thirty-two stations and a previous winter survey for comparison.
• Includes investigation of fine-scale variability at eight stations with three pairs of grabs each.
• CTD profiles provide vertical temperature and salinity data for stations throughout the entire bay.

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 the single study location in Jervis Bay.
