Benthic sediment surveys of inner Darwin Harbour (GA0358) and shallow water areas in and a

Geoscience Australia, AIMS, and the Northern Territory Government collected benthic sediment samples in inner Darwin Harbour (GA0358) and shallow waters in and around Bynoe Harbour (GA0359) between May 29 and June 19, 2017. This dataset comprises grain size measurements on seabed sediments. The surveys are part of a four-year (2014-2018) science program to collect baseline data for thematic habitat maps to support marine resource management.

Use Cases

• Model seabed habitat types based on sediment grain size data mentioned in the description.
• Establish environmental baselines for marine resource management decisions as described in the program goals.
• Analyze spatial distribution of sediment characteristics in Darwin and Bynoe Harbour areas.
• Support coastal and marine spatial planning using the thematic habitat maps the data is intended to enable.

Strengths

• Data collection involved multiple authoritative partners: Geoscience Australia, AIMS, and the Northern Territory Government.
• Surveys have a defined temporal scope from May 29 to June 19, 2017.
• Project is part of a structured, multi-year (2014-2018) science program with a clear objective for habitat mapping.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the specific harbour areas surveyed.
