X-ray Diffraction Data for 42 Surface Seabed Sediment Samples in Jervis Bay, NSW

42 samples of surface seabed sediment mineralogy from Jervis Bay, New South Wales, collected in June 2008. Geoscience Australia acquired the data during marine surveys from 2007 to 2009 to map seabed bathymetry and characterize benthic environments. The dataset likely contains mineral composition data for sediments from the top 0-2 cm of the seabed.

Use Cases

• Modeling physical surrogates for benthic biodiversity based on sediment mineralogy mentioned in the description
• Analyzing relationships between seabed sediment composition and infaunal diversity in a temperate embayment
• Characterizing benthic habitats by correlating mineralogical data with co-located video and photographic observations

Strengths

• Data is associated with peer-reviewed scientific publications cited in the description
• Samples are co-located with other survey data like bathymetry, video, and infauna sampling, enabling multi-modal analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
