Gray's Reef
National Marine Sanctuary

Gray's Reef National Marine Sanctuary is an ocean park teeming with life. The natural live-bottom habitats of the sanctuary are representative of others across the region. The sanctuary provides year-round opportunities for sport fishing, recreational diving, and boating. The research area within the sanctuary hosts one of the only designated no-take zones in the region, which makes Gray's Reef a catalyst for scientific research studying water quality, ocean noise, hurricane prediction, and climate change.

Gray's Reef is a marine oasis. On the surface, recreational anglers try for grouper, sea bass, and snapper, while a northern gannet flies overhead, and a NOAA weather buoy collects data. Beneath the waves, divers share the waters with a host of colorful tunicates, sponges, soft corals, and other residents of the live-bottom reef, like a loggerhead sea turtle, octopuses, nurse sharks, schools of spadefish, jellyfish, and North Atlantic right whales.

The reef's scattered rocky outcroppings and ledges provide home for an abundance of marine life, which form a dense carpet of living creatures called a "live bottom." This poster highlights the true beauty and importance of the waters surrounding Gray's Reef.
