Aquatic Substrate Spectral Library for Western Australian Sites

Harvey's 2009 PhD thesis contributed this spectral library of marine benthic habitats to the Australian National Spectral Database. Data was collected from Rottnest, Marmion, and Shoalwater sites during 2006-2007. The library is hosted by the Australian Ocean Data Network.

Use Cases

• Classify benthic habitat types from hyperspectral reflectance signatures using spectral matching algorithms.
• Train supervised classification models to map substrate composition (e.g., sand, seagrass, reef) across coastal imagery.
• Validate airborne or satellite hyperspectral data against in-situ spectral measurements from known substrates.
• Analyze spectral variability within a substrate class across the Rottnest, Marmion, and Shoalwater sampling locations.

Strengths

• Data originates from a peer-reviewed PhD thesis, providing academic rigor.
• Covers three distinct coastal sites in Western Australia for geographic comparison.
• Temporal coverage is specific to the 2006-2007 collection period.

Limitations

• The exact number of spectral samples, rows, or file size is not provided.
• Data is over 15 years old, which may limit relevance for detecting recent environmental change.
• Focus on oligotrophic, temperate waters may reduce applicability to other marine environments.
