 Coral reefs are among the most diverse ecosystems in the world, and many economies depend on them. They also help to buffer shorelines, protecting them from erosion. However, they are in danger of disappearing from an onslaught of different threats. The new partnership will build the first-ever coral reef-monitoring system to detect where reefs are changing, so action can be taken to mitigate effects.

The Remote Sensing Research Centre, University of Queensland The Remote Sensing Research Centre uses remotely sensed data, fieldwork, and spatial models to measure, map, and monitor biophysical properties in terrestrial, atmospheric, and aquatic environments to better understand and manage the Earth’s environments and resources. --------------- To learn more VISIT: sees.uq.edu.au/remote-sensing-research-centre Hawai’i Institute of Marine Biology The mission of the Hawai’i Institute of Marine Biology (HIMB) is to conduct multidisciplinary research and education in all aspects of tropical marine biology. HIMB continues to be a world leader in research to understand and conserve tropical marine ecosystems. HIMB is an independent research unit within the School of Ocean Earth Science and Technology (SOEST) at the University of Hawai’i, Mãnoa. --------------- To learn more VISIT: himb.hawaii.edu/about-us/ SUPPORT: Leonardo DiCaprio Foundation, the Nature Conservancy, and Paul G. Allen Philanthropies provided support. detect changes in coral reefs such as bleaching or destruction from coastal development. The Carnegie change-detection and alert system will be the first of its kind and will propel a global effort to slow and reverse coral reef losses. “Where there is effort, there is hope,” Asner said. “I’m tired of only seeing negative news about coral reefs. I want to focus on resilience as well as danger to highlight efforts, such as ours, to understand, manage, and conserve reef systems. Our new coral reef-monitoring system made possible in this project will be the first to detect where reefs are changing, and to direct action to mitigate losses.” In its first year, the partnership plans to produce the global mosaic, a global community engagement plan, and five site- based maps to validate the new image processing and mapping methodology. The pilot sites were chosen to represent a variety of reef types and health from across the globe where field verification data are readily available. They are Heron Island, Great Barrier Reef, Australia; Mo’orea, French Polynesia; Lighthouse Reef, Belize; West Hawaii Island, Hawaii; and Karimunjawa, Indonesia. “Seeing change is the first step in taking responsibility for it,” said Andrew Zolli, vice president for global impact initiatives at Planet. “By putting the most complete, up-to-date picture of the world’s corals in the hands of scientists, conservationists, and communities, we hope to accelerate action on the coral crisis before it’s too late.” Once the five sites are mapped and methodology refined, the partnership intends to scale the benthic and geomorphic mapping to regions in 2019 and then the entire globe in 2020. Also, in 2019 the use of artificial intelligence will be applied to detect changes on the reefs and alert conservationists and governments to the situation so that resources can be immediately engaged. Greg Asner and Robin Martin have accepted senior positions at Arizona State University, where Asner will establish a new Center for Global Discovery and Conservation Science, and Martin will be an associate professor. They are eager to keep connections open with the many colleagues at Carnegie with whom they have collaborated on both coral work and their mapping efforts.  Carnegie Science | Fall 2018 5   
