Layer: St. Thomas/St. John Index of Reef Quality (ID: 339)

Parent Layer: Local SCUBA Diver Knowledge

Name: St. Thomas/St. John Index of Reef Quality

Display Field: CLASS

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Data used to produce this layer were collected in 2014 by NOAA’s National Centers for Coastal Ocean Science (NCCOS). Data were collected from the population of occupational SCUBA divers in the U.S. Virgin Islands (n=87) on the value of particular reef areas, as well as the status of these reefs in terms of ecological health. Survey respondents provided spatial information on: 1) the presence of significant ecological and biological features on familiar reefs; 2) the influence of common ecological stressors on familiar reefs; and 3) the best reef areas for diving tourism, personal diving and research activities. Multiple data layers were created to summarize spatial data provided by survey respondents. These data were collected with the purpose of incorporation into a model to be used for prioritization of coral reefs in the U.S. Virgin Islands.This particular resource contains the Index of Reef Quality as perceived by professional SCUBA divers in the USVI. The reefs are classed either A or B depending upon the number of four different reef features/characteristics that a given cell contains. The four reef features are: Large Variety of Coral Species; Large Variety of Fish Species; Large Amount of Coral Cover; and, Large Amount of Physical Reef Structure.
