Coral Reefs - Guam

This dataset represents a subset of the global distribution of warm water coral reefs for the island of Guam and should be seen as an "interim" product. It has been compiled from a number of data sources which have been merged together by UNEP-WCMC and the WorldFish Centre in collaboration with WRI and TNC. It supersedes the dataset used in the World Atlas of Coral Reefs (2001), although some aspects of this product still originate from that data source. This amalgamated dataset has been created to further mobilise the Millennium Coral Reef Map Products and their validation. This data set should by no means replace the official release of the Millennium coral reef map and users should always check at the official sites for the most up-to-date available information. This dataset does not contain the full 5 level geomorphological categorization. In part, for the validated products, it maintains the simplified Reefbase subset but for the remaining areas i.e. the unvalidated data and data from other sources, there is only a single class to indicate coral reef.

When using these data, please cite the following:

UNEP-WCMC, WorldFish Centre, WRI, TNC (2010). Global distribution of warm-water coral reefs, compiled from multiple sources including the Millennium Coral Reef Mapping Project. Version 1.3.
