Giant Kelp Forest Surface Canopy Maps for Southern Australia, 2016–2023

Giant Kelp communities in Australia were declared an endangered marine community in 2012 due to a ~95% loss in eastern Tasmania. This dataset maps the surface canopy of these forests from 2016 to 2023 using 3 m resolution satellite imagery across Tasmania, Victoria, southern New South Wales, and eastern South Australia. The data was produced by the Australian Ocean Data Network and includes binary extent and continuous probability layers.

Use Cases

• Monitoring endangered marine community decline based on annual binary kelp extent maps.
• Modeling kelp forest probability and variability using continuous probability layers by year and zone.
• Assessing the impact of ocean warming and herbivory on kelp distribution across southern Australia.
• Validating and improving remote sensing machine learning workflows for coastal vegetation mapping.

Strengths

• Covers a critical 8-year time series from 2016 to 2023 for monitoring change.
• Uses high-resolution 3 m PlanetScope imagery processed with a two-pass machine learning workflow.
• Provides data across four jurisdictional regions in southern Australia.
• Includes both binary classification and continuous probability outputs for analysis flexibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the known historical range in southern Australia.
