2023 Coral Bleaching Guidance
Coral Restoration Consortium releases guidance to practitioners on coral bleaching Bleaching is reaching severe levels throughout the tropics with more reports coming in daily. This extreme heat stress due to the predicted El Niño, is arriving a month earlier than expected. Corals can recover from mild or short-term bleaching but long-term or extreme heat causes […]
Regional Coordinators Meeting – July 2023
The GCRMN is structured in ten regional nodes, which operate as independent entities around a regional coordinator. These node coordinators facilitate the communication within the region, workshops on monitoring and data management and contributions to global and regional GCRMN “Status and Trends of Coral Reefs” reports. Regional node coordinators interact with the GCRMN Core Team […]
Is El Niño on the horizon? What does it mean for coral reefs
Hard corals are particularly sensitive to marine heatwaves (a period of abnormally high ocean temperatures), as thermal stress can lead them to expel their symbiotic algae – zooxanthellae -, revealing their white calcium carbonate structure, a phenomenon called “coral bleaching”. As hard corals heavily depend on the energetic resources provided by their symbiotic algae, marine […]

New insights into Diadema mass mortality
Over the five last years, humanity has faced a new catastrophic pandemic with Covid-19. However, humans are not the only species to suffer from pandemics, and the impact of one pandemic is not limited to the species that it affects because of particular functions species fulfill within ecosystems. As such, a species extirpation following a […]
Coral Beaching on the Allen Coral Atlas
Today the Allen Coral Atlas released a new version of its coral bleaching monitoring system, including biweekly bleaching data from 2019 to the present. This unprecedented data release helps resource managers react to bleaching events as they occur, and decision makers as they prioritize areas for restoration and mitigation. “Coral bleaching is one of the […]
Call for Coral Reef Data: Pacific Region
Over the last 10 years, the Global Coral Reef Monitoring Network (GCRMN) has adopted a new approach, based on the analysis of standardized coral reef monitoring data. The recent “Status and Trends of Coral Reefs of the World: 2020” GCRMN report was produced utilizing this approach which has made it possible to estimate temporal changes […]
Western Indian Ocean Coral Reef Task Force Workshop
The regional coral reef networks in the Western Indian Ocean have been active since 1999, coordinating and reporting on coral reef monitoring activities through the Nairobi Convention Coral Reef Task Force (CRTF), and the Global Coral Reef Monitoring Network (GCRMN), with support from multiple sources. The partnership of the GCRMN, the Indian Ocean Commission (IOC-COI), […]
