Darwin Harbour Sediment Grain Size Measurements

Darwin Harbour Habitat Mapping Program sediment grain size data contains measurements from seabed samples collected in the Darwin and Bynoe Harbour regions. The dataset reports on 499 samples from 489 stations, collected by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government between 2011 and 2017. It was funded by the INPEX-led Ichthys LNG Project offset funds to support baseline habitat mapping and marine resource management.

Use Cases

• Analyze sediment_grain_size distribution across 489 sampling stations to model seabed habitat types.
• Correlate grain_size statistics with water depth and location data for coastal erosion studies.
• Use summary_statistics of grain size to establish environmental baselines for the Darwin Harbour region.
• Map spatial variability in sediment composition from samples collected between 2011 and 2017.

Strengths

• 499 sediment samples provide a substantial basis for spatial analysis
• Data collection spanned 6 years (2011-2017) across multiple surveys
• Samples originate from 489 distinct geographic stations

Limitations

• Specific column names and data types are not provided
• Sample size of 499 may be limited for high-resolution, site-specific modeling
• Data is static, covering a period ending in 2017
