Benthic Sediment Chemistry and Metabolism in Darwin and Bynoe Harbours, 2017

Between May 29 and June 19, 2017, benthic sediment sampling was conducted in inner Darwin Harbour and shallow waters around Bynoe Harbour. The dataset comprises total sediment metabolism, carbonate, organic isotope, and organic and inorganic element measurements on seabed sediments. This work was part of a four-year (2014-2018) science program led by the Northern Territory Government and supported by Geoscience Australia, AIMS, and the INPEX-led Ichthys LNG Project.

Use Cases

• Modeling sediment metabolism and nutrient cycling based on organic and inorganic element measurements.
• Mapping benthic habitats based on sediment carbonate and geochemical composition.
• Establishing environmental baselines for harbor management based on multi-parameter sediment surveys.
• Studying carbon dynamics in coastal sediments based on organic isotope data.

Strengths

• Data collection involved multiple authoritative partners: Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government.
• Surveys were conducted over a defined three-week period in 2017, providing a temporal snapshot.
• Measurements cover multiple sediment properties, including metabolism, carbonate, isotopes, and elements.

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.
