Cremated remains are mixed with cement to form features of the Reef, and memorial plaques are added.

The man-made reef, located three miles (5 km) off the coast of Florida's Key Biscayne, opened in 2007 after a number of difficulties, including permits.

The reef stretches across 16 acres (65,000 m2) of ocean floor designed as both a home for sea life and "a destination for divers".
