Jervis Bay Infauna and Geochemistry Survey Across Seasons

Thirty-two stations in Jervis Bay were sampled to collect paired geochemical and biological data, with eight stations having three replicate grabs to measure fine-scale variability. The survey combined new data with a previous winter survey (GA309) to investigate seasonal variation. Preliminary results indicated most physical variables and infaunal assemblages varied between seasons, with greater variation among stations than within replicates.

Use Cases

• Modeling biodiversity surrogates based on contemporaneous physical and biological data.
• Investigating seasonal variation in infaunal assemblages by combining data with a previous winter survey.
• Analyzing fine-scale spatial variability (at the scale of meters) using replicate grab samples.
• Studying vertical water column profiles using CTD data on temperature and salinity.

Strengths

• Survey design includes spatial replication at thirty-two stations and temporal replication by linking to a prior winter survey.
• Fine-scale variability is addressed with three pairs of grabs deployed at eight stations.
• CTD casts provide vertical profiles of temperature and salinity at each station.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for analysis.
