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 during multiple surveys between 2011 and 2017, funded by the INPEX-led Ichthys LNG Project and co-investors. The data are published in the Marine Sediments Database (MARS) with the permission of Geoscience Australia.
Use Cases
- Model seabed habitat types based on sediment grain size characteristics mentioned in the description.
- Establish environmental baselines for Darwin and Bynoe Harbour regions using the collated sediment data.
- Support marine resource management decisions with thematic habitat maps derived from the grain size statistics.
Strengths
- Contains 499 sediment samples from a defined geographic region.
- Data collection spans a 6-year period from 2011 to 2017, providing a temporal baseline.
- Project involved multiple authoritative institutions: Geoscience Australia, AIMS, and the Northern Territory Government.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to the specific harbour regions studied.
