Octopod on Submersible Arm
A deep-sea octopod wraps itself around a submersible’s robotic arm 2,300 meters (7,546 feet) down in the Gulf of Mexico. "Most octopuses will let you get close, maybe even touch them, but normally they'll try to run once the manipulator gets close," said Bruce Strickrott, pilot of the submersible Alvin. Explore more octopod content and learn more in our Deep Ocean Exploration section.

Deep-Sea Corals: NOAA Education Plans & Activities
Page 1Coral reefs are vibrant ecosystems teeming with color and life. Most grow in the warm sunlit waters of tropical seas. Beautiful and accessible, shallow water corals are beloved by the public and well known to scientists. In contrast, deep-sea corals are generally unknown and unappreciated. -
Views from the ROV Jason
Inside the control van for the remotely operated vehicle Jason, Dr. Brendan Roark and colleagues watch the ROV collecting deep-sea coral specimens. This NOAA expedition took place in November 2010 in the Gulf of Mexico and off the coast of Florida. Learn more about deep-sea corals in the multimedia feature "Coral Gardens of the Deep Sea."

Coral Growth Rings
Ultraviolet light illuminates the growth rings in a cross-section of a 44-year-old Primnoa resedaformis deep-sea coral collected off the coast of Newfoundland in about 400 m (1,312 ft) of water. Similar to tree trunks, cross-sections reveal coral-growth rings that can be used to determine their age.
