Jervis Bay Marine Biogeochemistry and Infauna Survey with Seasonal Replication

Jervis Bay, Australia, is the location for a marine survey collecting paired geochemical and biological samples. The dataset includes data from 32 stations in a defined grid, with fine-scale replicates at 8 stations, and vertical CTD profiles for temperature and salinity. The survey was conducted by Geoscience Australia to investigate seasonal variation by combining results with a prior winter survey, with samples processed by late 2009.

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 a meter scale.
• Analyzing seasonal changes in coastal biogeochemistry by comparing data from this survey with a previous winter survey.
• Assessing the effectiveness of environmental surrogates for biodiversity prediction based on contemporaneously collected physical and biological data.

Strengths

• Includes paired geochemical and biological samples from 32 stations, enabling direct correlation.
• Features fine-scale spatial replication with three pairs of grabs at 8 stations to assess meter-scale variability.
• Incorporates vertical water column profiles from CTD casts at stations throughout the bay.
• Designed for temporal analysis by being combined with data from a previous winter survey (GA309).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data collection concluded in 2009; freshness should be verified for contemporary applications.
