Benthic cover (habitat) maps are derived from aerial imagery, underwater photos, acoustic surveys, and data gathered from sediment samples. Shallow to moderate-depth benthic habitat information assists ecosystem-based marine resource management. Many habitats, including hard and soft corals, are home to a diversity of marine organisms, which provide many important ecosystem services, including fishing, tourism, water quality enhancement, and shoreline protection. Coral reef ecosystems and associated bottom types are under increasing pressure from environmental and anthropogenic stressors. Mitigating these threats requires analyzing their spatial distribution, making benthic habitat mapping a key component to the conservation and management activities of state and federal agencies.
