Jervis Bay Marine Biogeochemistry with Seasonal and Fine-Scale Replication

Thirty-two stations in Jervis Bay were sampled for paired geochemical and biological data, with eight stations having three replicate grabs to measure fine-scale variability. The survey, conducted by Geoscience Australia, was designed to be combined with a previous winter survey to investigate seasonal variation. Preliminary results from 2009 indicated that most physical variables and infaunal assemblages varied between seasons.

Use Cases

• Modeling abiotic surrogates for biological diversity based on paired environmental and infaunal data.
• Investigating seasonal variation in marine ecosystems by comparing data from two surveys.
• Analyzing fine-scale spatial variability in infaunal assemblages at the meter scale using replicate grabs.
• Studying vertical water column profiles using CTD-derived temperature and salinity data.

Strengths

• Survey design includes spatial replication at thirty-two stations and temporal replication across two seasons.
• Fine-scale variability is addressed with three replicate grabs at eight stations.
• Paired geochemical and biological samples were collected contemporaneously at each station.
• CTD casts provide vertical profiles of temperature and salinity throughout the bay.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; the last metadata update is dated 2026-04-30.
