Darwin Harbour Sediment Grain Size Data from 2011-2017 Surveys

Sediment grain size data and summary statistics for the greater Darwin Harbour region, including Bynoe Harbour. The data were derived from 499 seabed samples collected at 489 stations during multiple surveys between 2011 and 2017. This baseline habitat mapping program was funded by the INPEX-led Ichthys LNG Project and co-invested by Geoscience Australia and the Australian Institute of Marine Science.

Use Cases

• Modeling seabed habitat distribution based on sediment grain size characteristics.
• Analyzing sediment composition for environmental baseline studies in Darwin Harbour.
• Supporting marine resource management decisions with collated baseline data.
• Creating thematic habitat maps for the Darwin and Bynoe Harbour regions.

Strengths

• Contains 499 sediment samples from 489 stations, providing a substantial sample size.
• Data collected over a 6-year period (2011-2017), offering temporal context.
• Published with the permission of the CEO, Geoscience Australia, indicating official provenance.
• Funded by a multi-party collaboration including government and research institutions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
