Healthy coral reefs are some of the most biodiverse ecosystems on the planet, leading some to call reefs the rainforests of the sea. Coral reefs are also threatened by ocean acidification caused by climate change, pollution, overfishing, and more. To aid conservation work, the Khaled bin Sultan Living Oceans Foundation (LOF; see the 3-13-2018 Scout Report) has created this wonderful interactive atlas of coral reefs in remote locations around the world. Visitors can explore the map by selecting a pin or using the menu to choose a location, then zoom into a specific island area within that location to view a colorful detailed map of its reefs different habitat areas, many of which are accompanied by underwater videos. This online map, which accompanies an April 2019 research article published in the journal Coral Reefs, was created using remote sensing and field observations as part of LOF's Global Reef Expedition, a ten-year project surveying the world's remotest reefs. In addition to its visual appeal, the map also includes GIS tools enabling users to measure and analyze specific reef habitats. These and other features are explained in the map's useful help section.
