Deep-Sea Corals and Sponge Habitat in the Aleutian Islands
Hear Christina Conrath, a research biologist with the Alaska Fisheries Science Center, recap some of the incredible diversity of life seen during deep-sea coral and sponge surveys in the Aleutian Islands during the summer of 2023.
Corals Take a Ride on a 'Deep Sea Elevator' - Deepwater Horizon Restoration
A Deepwater Horizon restoration project is restoring corals in the Gulf of Mexico injured by the 2010 oil spill, using innovative techniques. The work is part of the Mesophotic Deep Benthic Communities portfolio of projects.
Climate Change & Habitat Loss: Fisheries at Risk
Habitat restoration experts discuss the challenges coastal habitats face from climate change and what NOAA is doing to address them
Repairing the Reef: West Hawai’i Focuses on Habitat
On Hawai’i Island, NOAA is partnering with The Nature Conservancy, local communities, government agencies, non-profit organizations and businesses to restore habitat and improve coral reef health along with other natural and cultural resources.
Discover the Deep-Sea Corals of Maine
Scientists with NOAA Fisheries discover deep-sea coral gardens close to shore (25 miles) and shallow (700 feet). Unknown until 2014, these Gulf of Maine spots abound with corals, cod, and a snapping goosefish. Look out!
Corals: The Bottom Line
A montage of Atlantic, Gulf of Mexico, Caribbean and Indo-Pacific corals in celebration of NOAA Fisheries' Corals Week: impacts and threats to corals as well as reef restoration efforts by NOAA and partners.
Habitat Exploration: Deep-Sea Corals
More than 70 underwater canyons exist off the northeastern coast of the US, some more than three miles deep. In this video, journey to the deep and discover new species of deep-sea coral and more through the eye of a remotely operated vehicle (ROV).
2013 Okeanos Explorer NE Canyons Coral Expedition
In 2013 the NOAA Ship Okeanos Explorer used an ROV to conduct visual surveys in canyons and a seamount off the Northeastern US seaboard. 31 ROV dives from 490 to 3,300 meters (1,608 to 10,827 feet) were completed.
2012 West Coast deep-sea coral research cruise
In 2012 NOAA and partners participated in a research cruise off the West Coast to explore and map deep-sea corals and sponges, associated fish and invertebrates, and document impacts from marine debris and bottom contact fishing gear.
Coral Forests of the Deep
Deep-sea corals provide habitats for a huge variety of organisms. These ecosystems are also important for commercial fish stocks. Yet for all their value, these reefs are at risk, due to trawling, ocean acidicification and other human activities.
Staghorn and elkhorn coral, which are the building blocks of reefs in the Caribbean and Florida Keys, have become threatened species. NOAA and its partners started a coral restoration effort to transplant and restore thousands of coral colonies.
