Samoan Reefs: Some Major Issues • Natural & human impacts – Crown-of-thorns invasion, hurricanes – Illegal fishing, sewage outfall • Largely unexplored below depths of ~3060 m – no comprehensive documentation of the plants, animals, and submarine topography. • Very little known of shelf-edge (50 -120 m deep) coral reef habitats throughout the world
