Seabed Geochemical and Physical Variables from Eastern Bonaparte Gulf, 2009-2010

Geoscience Australia collected 124 seabed samples in the eastern Bonaparte Gulf during 2009 and 2010. The dataset comprises 74 physical and geochemical variables describing organic matter and sediment properties, used to analyze links to benthic biodiversity. Clustering methods were applied to this data to identify patterns influencing ecosystem processes.

Use Cases

• Characterizing benthic habitats based on physical and geochemical seabed properties mentioned in the description
• Analyzing relationships between sediment geochemistry (e.g., organic matter reactivity, grain size) and infauna biodiversity
• Identifying seabed geohazards and unique habitats for marine conservation planning
• Studying cross-shelf transitions in sediment composition and energy levels

Strengths

• Dataset includes 124 distinct seabed samples
• Each sample is described by 74 physical and geochemical variables
• Data is linked to infauna observations for ecological validation
• Surveys were conducted by the national agency Geoscience Australia

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data freshness should be verified; last metadata update is 2026-06-16
