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

Satellite-derived maps of Giant Kelp surface canopy extent and probability from 2016 to 2023 across Tasmania, Victoria, southern New South Wales, and eastern South Australia. The data was produced by the Australian Ocean Data Network using a machine learning workflow on 3-meter resolution PlanetScope imagery. It provides binary extent and continuous probability layers to monitor this endangered marine community.

Use Cases

• Monitoring changes in endangered Giant Kelp forest extent based on annual binary kelp extent layers.
• Analyzing kelp canopy probability for ecological modeling based on continuous probability layers.
• Assessing the impact of ocean warming and other threats on kelp distribution over the 2016–2023 period.
• Validating remote sensing techniques for marine habitat mapping using the described machine learning workflow.

Strengths

• Covers a 7-year time series from 2016 to 2023 for temporal analysis.
• Uses high-resolution 3-meter satellite imagery for detailed spatial mapping.
• Provides both binary extent and continuous probability data layers for different analytical needs.
• Covers a broad geographic area across four Australian states/territories.

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 data_gov_au, focusing on known historical ranges.
