Caribbean Coral Reef Ecosystems Program Caribbean Coral Reef Ecosystems Program The Caribbean Coral Reef Ecosystems (CCRE) program began with a collaborative field project conceived by six National Museum of Natural History scientists during the early 1970s. The scientists interests included a range of disciplines central to reef ecology, including: invertebrate and vertebrate zoology, botany, carbonate geology, and paleobiology.
