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

May 29 to June 19, 2017 surveys of inner Darwin Harbour and Bynoe Harbour collected benthic sediment samples. The dataset comprises area-based rates of total carbon dioxide production and oxygen uptake in marine sediments. This work was part of a four-year (2014-2018) science program led by the Northern Territory Government, supported by the INPEX-led Ichthys LNG Project, and involved Geoscience Australia, AIMS, and NT DENR.

Use Cases

• Modeling carbon cycling in coastal ecosystems based on sediment carbon dioxide production rates.
• Assessing benthic habitat health based on sediment oxygen uptake measurements.
• Creating thematic habitat maps for marine resource management based on the collected baseline data.
• Analyzing the impact of development projects on near-shore marine environments based on the survey's temporal and spatial scope.

Strengths

• Data collected during a defined three-week period from May 29 to June 19, 2017.
• Partnership involves multiple authoritative institutions: Geoscience Australia, AIMS, and the Northern Territory Government.
• Supports a defined four-year science program (2014-2018) aimed at creating management tools.

Limitations

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