Benthic Sediment Grain Size Measurements for Darwin and Bynoe Harbours, 2017

May 29 to June 19, 2017 surveys collected seabed sediment samples in inner Darwin Harbour (GA0358) and shallow water areas in and around Bynoe Harbour (GA0359). The dataset comprises grain size measurements and was conducted by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government. This work is part of a four-year (2014-2018) science program to create baseline habitat maps for marine resource management.

Use Cases

• Model seabed habitat distribution based on sediment grain size data.
• Analyze sediment transport patterns in shallow harbour environments.
• Establish environmental baselines for marine resource management decisions.
• Correlate benthic sediment characteristics with other marine survey data.

Strengths

• Data collected during a defined three-week survey period from May 29 to June 19, 2017.
• Produced through a multi-institutional partnership involving Geoscience Australia, AIMS, and the NT Government.
• Part of a structured four-year (2014-2018) science program with a clear management objective.

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 and temporal bias inherent to the specific 2017 survey locations and period.
