499 sediment samples from 489 stations in the greater Darwin and Bynoe Harbour regions, collected between 2011 and 2017. The data, including grain size measurements and summary statistics, were derived from seabed samples as part of a baseline habitat mapping program funded by the INPEX-led Ichthys LNG Project and co-investors. This dataset is published with the permission of the CEO, Geoscience Australia and is intended to underpin marine resource management decisions.
Use Cases
- Model seabed habitat types based on sediment grain size characteristics mentioned in the description.
- Establish baseline environmental conditions for the Darwin Harbour region to inform management decisions.
- Analyze spatial patterns in sediment composition for marine geological studies.
- Support thematic habitat map creation using collated grain size data.
Strengths
- Data from 499 samples provides a substantial baseline for the study region.
- Samples were collected over a 6-year period (2011-2017) across multiple surveys, suggesting temporal and spatial coverage.
- Data is integrated into the Marine Sediments Database (MARS), indicating a degree of standardization.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for specific analytical needs.
