Darwin and Bynoe Harbour regions contain sediment grain size data and summary statistics derived from seabed samples. A total of 499 samples from 489 stations were collected by Geoscience Australia, AIMS, and the Northern Territory Government between 2011 and 2017. The data were funded by the Ichthys LNG Project and are published in the Marine Sediments Database (MARS).
Use Cases
- Create baseline habitat maps based on sediment grain size distribution.
- Model seabed stability and sediment transport patterns based on grain size statistics.
- Inform marine resource management decisions based on collated baseline environmental data.
- Study long-term changes in marine environments based on data collected over a six-year period.
Strengths
- 499 sediment samples provide a substantial baseline.
- Data collection spanned six years (2011-2017) across multiple surveys.
- Project involved multiple authoritative agencies: Geoscience Australia, AIMS, and the Northern Territory Government.
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 Darwin Harbour region.
