Seabed Topographic Relief Data for the Van Diemen Rise

Topographic relief data from seabed mapping surveys on the Van Diemen Rise in the eastern Joseph Bonaparte Gulf of the Timor Sea. The dataset was created by Geoscience Australia and the Australian Institute of Marine Science through surveys conducted in 2009 and 2010. It integrates geological and biological data from four study areas across the outer to inner shelf.

Use Cases

• Model relationships between topographic relief features and macro-benthic community structure.
• Analyze correlations between seabed geophysical data and sedimentological or geochemical properties.
• Investigate biodiversity patterns across the outer to inner shelf gradient using integrated geological and biological survey data.
• Use bathymetric relief data as input for habitat suitability models of infaunal species.

Strengths

• Data integrates geological (sedimentological, geochemical, geophysical) and biological (benthic diversity) measurements from the same surveys.
• Surveys cover four distinct study areas across the outer to inner shelf, providing spatial gradient analysis.

Limitations

• Specific row counts, column details, and sample sizes are not provided.
• Data is from 2009-2010 surveys and may not reflect current seabed conditions.
