The Blake Plateau, located approximately 80–200 miles off the southeastern U.S. coast, is home to the world’s largest deep-sea coral province. In this chapter, learners go behind the scenes of deep-sea exploration to discover the tools, technologies, and people that make it possible to study life nearly a mile beneath the ocean’s surface. From robotic vehicles to high-resolution seafloor maps, scientists are uncovering deep-sea coral habitats, unique geological features, and new insights into how the Blake Plateau functions as a living ecosystem.
