499 sediment samples from seabed stations in Darwin and Bynoe Harbour regions were collected between 2011 and 2017. Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government derived this grain size data as part of a baseline habitat mapping program funded by the INPEX-led Ichthys LNG Project. The data is published in the Marine Sediments Database (MARS) to underpin marine resource management decisions.
Use Cases
- Model seabed habitat suitability based on sediment grain size characteristics mentioned in the description.
- Establish environmental baselines for impact assessments using the multi-year survey data.
- Inform marine resource management decisions with thematic habitat maps derived from the collated baseline data.
Strengths
- 499 sediment samples provide a substantial observational basis for the region.
- Data collection spanned 6 years (2011-2017) across multiple surveys, offering temporal depth.
- The program involved collaboration between three major scientific institutions: Geoscience Australia, AIMS, and NTG-DENR.
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.
