GA0356: Outer Darwin Harbour Shallow Water Sediment Survey 2016

A benthic sediment sampling survey conducted from 03 July to 14 September 2016 in the nearshore areas of outer Darwin Harbour. The survey collected 200 seabed sediment samples for grain size, inorganic elemental, and organic matter analyses, with metadata for seagrass and hardground observations. It was undertaken by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government as part of a four-year science program from 2014 to 2018.

Use Cases

• Create thematic habitat maps based on interpolated abiotic parameters from sediment data.
• Analyze seabed composition for grain size and inorganic elemental content.
• Assess organic matter concentration, source, and reactivity in marine sediments.
• Update seagrass databases with observational metadata collected during the survey.
• Support marine resource management decisions with baseline environmental data.

Strengths

• 200 seabed sediment samples collected for detailed analysis.
• Survey conducted as part of a multi-year (2014-2018) science program involving multiple government and research partners.
• Data includes location maps and comprehensive metadata for samples and observations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF and DOCX formats, which may require extraction for computational analysis.
