Timor Sea Seabed Relief Data from Multibeam Surveys, 2009-2010

Van Diemen Rise in the eastern Joseph Bonaparte Gulf of the Timor Sea contains topographic relief data from seabed mapping surveys. Geoscience Australia and the Australian Institute of Marine Science conducted the surveys in 2009 and 2010, obtaining geological and biological data across four study areas from the outer to inner shelf. The data provides context for the benthic biodiversity of the Van Diemen Rise and the wider northern Australian marine region.

Use Cases

• Modeling seabed hardness based on topographic relief and backscatter data mentioned in the description
• Investigating relationships between physical environment and benthic community structure as described
• Providing regional context for biodiversity prediction in the Arafura-Timor Sea
• Characterizing seabed substrates across shelf gradients using the referenced processing techniques

Strengths

• Data collected over two consecutive years (2009 and 2010) providing temporal context
• Surveys cover four distinct study areas across the outer to inner shelf
• Integrated geological (sedimentological, geochemical, geophysical) and biological (macro-benthic, infaunal) data collection
• Processing methodologies are documented in a referenced Geoscience Australia record (2013/11)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
