Cordell Bank
National Marine Sanctuary

Cordell Bank National Marine Sanctuary is entirely offshore. Within its 1,286 square miles, the sanctuary protects soft seafloor habitat, a rocky bank, deep sea canyons, and communities of wildlife throughout. Its surface waters are feeding areas for local and migratory seabirds and marine mammals.
