The objective of The Atlantic and Gulf Rapid Reef Assessment (AGRRA) coral monitoring is to assess the size and overall condition of corals ≥ 4 cm to help evaluate important structural and functional attributes of tropical western Atlantic coral reefs. Data collected can provide information representative of large areas, like shelves, islands, countries or ecoregions. The coral monitoring surveys can be performed by snorkeling (
Show moreThe objective of The Atlantic and Gulf Rapid Reef Assessment (AGRRA) coral monitoring is to assess the size and overall condition of corals ≥ 4 cm to help evaluate important structural and functional attributes of tropical western Atlantic coral reefs. Data collected can provide information representative of large areas, like shelves, islands, countries or ecoregions. The coral monitoring surveys can be performed by snorkeling (< 1.5 m), but SCUBA is now recommended for most assessments with diver expertise ranging from novice to highly trained. Survey sites should be chosen randomly within a geomorphic zone of a reef on an insular or continental shelf within one of twelve marine shelf ecoregions of the Tropical Northwestern province of the Tropical Atlantic biogeographic realm. The spatial extent of a site is about 200 m x 200 m and zones of maximum reef development are highly recommended. Recording of exact location using GPS is critical for data quality and consistency. Surveys are completed to assess coral health, recruitments, size, and species. Although single metrics are insufficient to measure whole coral system health due to the highly dynamic nature of reefs, the information collected can indirectly measure environmental quality of the reef and assist in understanding the effects of local and regional stressors. The use of trained volunteer divers whether amateur or professional provides a wealth of information in a cost friendly manner and the data collected from over 3,000 surveys is available in an open-access public database. Information collected from monitoring surveys has become a key source of scientific data used in other research programs, reef policies, legislation, management and conservation.
