NOAA researchers have mapped the largest deep-sea coral reef habitat discovered to date, located on the Blake Plateau off the U.S. Atlantic coast. The area covers 6.4 million acres and provides a critical habitat for diverse marine species in the deep ocean.
TLDR: Scientists have identified a massive deep-sea coral reef province spanning 6.4 million acres off the U.S. Southeast coast. Using advanced sonar and ROVs, the NOAA-led team revealed a vast, continuous ecosystem of cold-water corals that supports significant biodiversity in the dark depths of the Atlantic.
The National Oceanic and Atmospheric Administration (NOAA) recently announced the completion of a multi-year mapping project that has revealed the largest deep-sea coral reef province discovered to date. Situated on the Blake Plateau off the coast of the Southeastern United States, this vast underwater landscape spans approximately 6.4 million acres. The area, which is roughly the size of Vermont, contains a nearly continuous distribution of coral mounds that have remained largely hidden from the scientific community until now.
This discovery is the culmination of a collaborative effort involving NOAA Ocean Exploration, the Bureau of Ocean Energy Management, and the U.S. Geological Survey. Researchers utilized high-resolution multibeam sonar mapping and 23 submersible dives conducted by the NOAA Ship Okeanos Explorer. By synthesizing data from 31 separate sonar surveys, the team created a comprehensive map of the seafloor, identifying 83,908 individual coral mound peaks. The sonar data was processed using advanced bathymetric software to distinguish between biological mounds and geological features. This precision allowed the team to delineate the boundaries of the reef province with unprecedented accuracy.
Deep-sea corals, unlike their shallow-water counterparts, exist in a world of perpetual darkness at depths ranging from 200 to 1,000 meters. Because they lack the symbiotic algae that require sunlight for photosynthesis, these corals survive by filtering organic particles and plankton from the surrounding water. The primary reef-building species in this region, Lophelia pertusa, creates intricate calcium carbonate structures that provide essential habitat for a diverse array of fish, crustaceans, and other marine invertebrates.
The Blake Plateau is a broad, flat feature of the continental shelf located between North Carolina and Florida. The newly mapped region, often referred to as “Million Mounds,” represents a significant expansion of known coral habitats. The mounds themselves vary in size, with some reaching heights of nearly 100 meters and stretching for several kilometers. These structures are not merely geological formations but are living ecosystems that have developed over thousands of years.
The mapping effort was part of the DEEP SEARCH project, which stands for Deep Sea Exploration and Research of Coral, Canyon, and Cold Seep Habitats. This initiative aimed to improve the understanding of the offshore resources along the U.S. East Coast. The use of Remotely Operated Vehicles (ROVs) allowed scientists to observe the reefs in situ, providing visual confirmation of the sonar data. The ROV Deep Discoverer provided the high-definition video necessary to verify the presence of live coral on the structures identified by sonar. These visual surveys also documented the presence of commercially important fish species, suggesting the reefs play a vital role in regional fisheries.
The implications of this discovery are significant for marine conservation and resource management. Deep-sea coral reefs are slow-growing and highly sensitive to physical disturbances, such as bottom trawling or energy development. They are also vulnerable to the effects of ocean acidification and rising water temperatures, which can inhibit the ability of corals to build their skeletons. Understanding the full extent of these habitats is a critical first step in developing strategies to protect them from anthropogenic threats.
Future research will focus on the ecological connectivity between the Blake Plateau and other deep-sea habitats in the Atlantic. Scientists are interested in how larvae from these reefs disperse and colonize other areas, as well as the role these ecosystems play in the broader carbon cycle. As oceanographic technology continues to advance, researchers expect to find more hidden biological hotspots that challenge current understandings of deep-ocean biodiversity.
