Benthic Sediment Surveys of Darwin and Bynoe Harbour (2017)

285 seabed sediment samples were collected from inner Darwin Harbour and shallow water areas in and around Bynoe Harbour between 29 May and 16 August 2017. The surveys were conducted by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government as part of a four-year science program to collect baseline environmental data. The data includes grain size, inorganic elemental analyses, organic matter measures, and seagrass observations for habitat mapping.

Use Cases

• Creating thematic habitat maps based on sediment and seagrass observation data.
• Analyzing seabed composition for grain size and inorganic elemental properties.
• Establishing environmental baselines for marine resource management decisions.
• Integrating sediment data with multibeam echosounder and video transect data for comprehensive mapping.

Strengths

• Contains 285 seabed sediment samples with associated metadata.
• Part of a multi-year (2014-2018) science program involving major institutions like Geoscience Australia and AIMS.
• Data includes seagrass and hardground observations, with seagrass data incorporated into a government database.

Limitations

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