Sediment grain size data and summary statistics for the greater Darwin Harbour region, 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. This baseline data was funded by the INPEX-led Ichthys LNG Project to support habitat mapping and marine resource management.
Use Cases
- Modeling sediment transport and deposition based on grain size distribution.
- Creating thematic habitat maps for marine resource management as described in the program intent.
- Establishing environmental baselines for the Darwin and Bynoe Harbour regions.
- Analyzing seabed composition for geological or ecological studies.
Strengths
- Contains 499 sediment samples from a defined geographic region.
- Data collection spanned multiple surveys over a 6-year period (2011-2017).
- Published with the permission of the CEO of Geoscience Australia, indicating formal approval.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
