Global Coral Reef Monitoring Network

GCRMN works through a global network to strengthen the provision of best available scientific information on and communication of the status and trends of coral reef ecosystems, for their conservation and management. GCRMN is the world's premier coral reef data network, bringing together a range of government and non-government partners in tracking status and trends of the world's coral reefs. It covers biophysical variables as well as socioeconomic variables, through the 'SocMon' initiative. The main activity is the preparation of regional and global periodic assessments on the status and trends of coral reefs. Established by ICRI, supported by UN.
