Charting “Million Mounds” of Deep-Sea Coral

Exploration Note Summary:

Introduce your students to the wonders of the deep sea with these exploration notes on the “Million Mounds” coral region. Located 100 miles off the southeastern U.S. coast, this vast ecosystem of Lophelia pertusa corals functions as an underwater “old-growth forest,” providing complex habitats and shelter for diverse marine life. This resource introduces students to the advanced multibeam sonar mapping and remotely operated vehicles (ROVs) used to study these ancient mounds, which thrive in total darkness 600 to 800 meters below the surface. Perfect for lessons on marine biology, oceanography, and modern scientific technology, this reading offers a real-world look at how scientists discover, map, and understand the planet’s hidden deep-sea treasures.
