Darwin Harbour Sediment Grain Size Data from 2011-2017 Surveys

Geoscience Australia's Darwin Harbour Habitat Mapping Program contains sediment grain size data for the greater Darwin Harbour and Bynoe Harbour region. The dataset includes 499 samples from 489 stations, collected between 2011 and 2017 by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government. These baseline data were funded by the INPEX-led Ichthys LNG Project to underpin marine habitat mapping and resource management decisions.

Use Cases

• Model seabed habitat distribution based on sediment grain size characteristics.
• Analyze spatial patterns in sediment composition for marine resource management.
• Establish environmental baselines for impact assessment using the 2011-2017 time range.
• Correlate sediment properties with other marine habitat mapping themes.

Strengths

• Contains 499 sediment samples from 489 stations, providing a substantial point dataset.
• Data collection spans a 6-year period from 2011 to 2017, offering a temporal baseline.
• Produced by authoritative institutions: Geoscience Australia, AIMS, and the NT Government.
• Explicitly intended for creating thematic habitat maps to support management decisions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known (499 samples), but specific data formats and internal structure require inspection.
• Data may reflect geographic bias specific to the Darwin and Bynoe Harbour regions.
