Deep-Sea Diving - Discover New England Seamounts

Deep-sea diving, in modern times, includes diving by means of remote submersibles like Alvin. This video, from an exploration of the New England Seamounts (a chain of extinct, underwater volcanoes located about 500 miles off the east coast of North America) reveals beautiful coral colonies.

According to NOAA:

The Alvin submersible dives on the New England Seamount chain found plentiful coral colonys of whip coral, parasol coral, and beautiful spiraling Iridogorgia. These coral collections are made up of hundreds of tiny polyps, arranged in precise geometric patterns.
