GA0358/GA0359: Benthic Sediment Chlorin Measurements in Darwin and Bynoe Harbours, 2017

Benthic sediment samples from inner Darwin Harbour and shallow waters around Bynoe Harbour were collected between May 29 and June 19, 2017. The dataset comprises total chlorin and chlorin index measurements on seabed sediments. This work was conducted by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government as part of a four-year science program from 2014-2018.

Use Cases

• Modeling benthic habitat health based on chlorin index measurements.
• Creating thematic habitat maps for marine resource management using baseline sediment chemistry data.
• Analyzing spatial patterns of organic matter in seabed sediments within the surveyed harbour regions.
• Establishing environmental baselines for future impact assessments in Darwin and Bynoe Harbours.

Strengths

• Data collection involved multiple authoritative partners: Geoscience Australia, AIMS, and the NT Government.
• Surveys were conducted over a defined three-week period in 2017, providing a temporal snapshot.
• The dataset is part of a defined four-year (2014-2018) science program aimed at creating management-ready habitat maps.

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 timeframe.
