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 […]
