The Ocean Health Index (OHI) is a comprehensive framework for evaluating the health of the world’s oceans. Using the best available data, methods, and analytical tools, OHI assessments synthesize data into concrete scores organized around 10 goals for the sustainable use of healthy oceans: Food Provision, Artisanal Fishing, Natural products, Carbon Storage, Coastal Protection, Tourism & Recreation, Livelihoods & Economies, Sense of Place, Clean Waters, and Biodiversity. Updating each year, the latest OHI information is available from NCEAS in Esri’s Living Atlas.
