Shallow Marine Areas Mask for Northern Australia and GBR Derived from Sentinel-2 Imagery (NESP MaC 3.17, AIMS)

This dataset represents a comprehensive mapping of shallow marine areas across Northern Australia and the Great Barrier Reef, encompassing intertidal zones, shallow subtidal habitats (down to approximately 5 meters depth in turbid waters), and offshore reef features visible at depths of up to 40 meters in clear waters. Derived from Sentinel-2 composite imagery, it identifies benthic areas where seafloor features are visible in the satellite imagery, providing a mask for mapping of marine habitats from Sentinel 2 imagery. Covering a broad geographic extent from Western Australia to the east coast of Queensland, including remote territories such as Christmas Island, Cocos (Keeling) Islands, Lord Howe Island, and Norfolk Island, this dataset serves as a critical input for reef boundary mapping and shallow water habitat modelling.
