The ocean is an ecological, social, and economic support system that touches nearly every aspect of our lives. Understanding how it can sustain our planet is vital for understanding our future. Through data visualization, ESRI interactive mapping tools, and beautifully informative infographics, the Ocean Health Index website illustrates the dynamic relationship between the ocean and humanity. The website serves as a tool for researchers, policy makers and the public to understand the current state of the world's oceans, and identify how we can better manage our relationship with them.
