Sediment oxygen demand measurements from the upper 2 cm of seabed sediments collected during two surveys in 2009 and 2010. The surveys SOL4934 and SOL5117 were conducted in the eastern Joseph Bonaparte Gulf, Northern Australia, in collaboration with the Australian Institute of Marine Science. The dataset was produced to support biophysical mapping and the identification of geohazards and sensitive environments.
Use Cases
- Assessing seabed environmental stability for offshore infrastructure planning based on sediment oxygen demand measurements.
- Identifying potential geohazards in tropical marine environments based on seabed sediment composition data.
- Developing biophysical maps of complex seabed environments based on survey data from the Van Diemen Rise.
- Supporting sustainable resource use decisions based on scientific information on seabed biological assemblages.
Strengths
- Data originates from two dedicated scientific surveys (SOL4934 and SOL5117) conducted in August-September 2009 and July-August 2010.
- Collaboration involved multiple authoritative institutions, including the Australian Institute of Marine Science, the RAN Australian Hydrographic Office, and the Geological Survey of Canada.
- The dataset is linked to specific published post-survey reports (Geoscience Australia Records 2010/09 and 2011/08).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific survey areas in the eastern Joseph Bonaparte Gulf.
