September 2, 2015 — Most people when they hear the word “coral” think of shallow, turquoise water and colorful reefs populated by bright tropical fish. Now think again. In the cold and often dark Gulf of Maine, spectacular cold-water coral formations, some of which may be hundreds if not thousands of years old, are just now being mapped and explored.

Most cold-water corals lie in the very deep submarine canyons and seamounts along the edge of the continental shelf. Yet they also occur in deep areas of the Gulf that are closer to shore, such as Jordan Basin. Cold-water corals typically are soft corals with flexible skeletons, unlike the coral species that build tropical reefs. Fishermen have long been familiar with taller coral outcroppings, which they called “trees,” on Georges Bank and other shallow-water areas in the Gulf.

Since 2013 scientists funded through NOAA’s Deep Sea Coral Research and Technology Program have been conducting research cruises in the Gulf of Maine using remotely controlled underwater vehicles and multibeam sonar to identify cold-water coral communities. This year during a ten-day research cruise, scientists from the University of Maine, the Northeast Fisheries Science Center, and the Northeast Underwater Research, Technology and Education Center at the University of Connecticut looked at three areas: Outer Schoodic Ridge, the Mount Desert Rock area and the Georges Basin region.
