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

A 2009/2010 seabed mapping survey by Geoscience Australia collected 124 samples from the eastern Bonaparte Gulf. The dataset comprises 74 physical and geochemical variables describing organic matter and sediment properties, used to analyze links to benthic biodiversity. Results were presented at the GEOHAB conference in May 2014.

Use Cases

• Cluster analysis of seabed habitats based on 74 physical and geochemical variables.
• Modeling relationships between sediment geochemistry (e.g., organic matter reactivity, grain size) and infauna biodiversity.
• Identifying geochemical indicators for unique or sensitive benthic habitats relevant to conservation planning.
• Assessing potential geohazards and seabed conditions for offshore infrastructure development.

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.
• Survey was conducted by the national authority Geoscience Australia.

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.
