Jervis Bay Seabed Sediment X-ray Fluorescence and Surface Area Data (2008-2009)

128 surface sediment samples from Jervis Bay, NSW, analyzed for major, minor, and trace elements using x-ray fluorescence, with accompanying sediment surface area measurements. Geoscience Australia collected the data during marine surveys in 2007, 2008, and 2009 to characterize benthic environments. The work is detailed in peer-reviewed publications from 2011 and 2012.

Use Cases

• Modeling benthic biodiversity using physical sediment surrogates based on elemental composition and surface area.
• Characterizing seabed sediment geochemistry for environmental baseline studies based on x-ray fluorescence data.
• Mapping relationships between sediment properties and benthic habitats based on co-located sampling described in the survey.
• Analyzing temporal changes in sediment composition across the June 2008, August 2008, and February 2009 sampling periods.

Strengths

• 128 sediment samples provide a substantive collection for analysis.
• Data is linked to specific, published scientific research from 2011 and 2012.
• Surveys incorporated multiple data types including bathymetry, video, and infauna sampling, suggesting contextual richness.

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 updated metadata date is 2026-05-21.
