Darwin Harbour Sediment Grain Size Data from 2011-2017 Surveys

Darwin and Bynoe Harbour regions contain sediment grain size data from 499 seabed samples. These samples were collected during multiple surveys by Geoscience Australia, AIMS, and the Northern Territory Government between 2011 and 2017. The data were funded by the Ichthys LNG Project offset funds and are published in the Marine Sediments Database.

Use Cases

• Modeling seabed habitat types based on sediment grain size characteristics.
• Establishing environmental baselines for marine resource management decisions.
• Analyzing sediment distribution patterns across the Darwin Harbour region.

Strengths

• Contains 499 sediment samples from 489 stations, providing spatial coverage.
• Data collection spanned 6 years (2011-2017), offering a temporal baseline.
• Derived from a multi-agency collaboration involving 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.
