With a definition of ‘healthy’ that includes sustainable human use, the OHI scores locations from 0-100 depending on how sustainably their waters provide a suite of benefits to people. The OHI framework was first used to assess all coastal nations globally, and was published in 2012 (Halpern et al. 2012, Nature).
Following the 2012 publication, the OHI framework has been used to assess smaller-scale locations, most often states or provinces within a single nation. These smaller spatial scales often have information that better represents local characteristics of marine systems and are also often the scale at which policy decisions are made.
To date, eleven assessments using the OHI framework have been completed at global, national, and regional scales, four of which have been led by independent academic or government groups. To facilitate these assessments, we have developed a suite of open-source tools and instruction. The OHI Toolbox provides structure for data organization and storage, with data processing and goal modeling done in the programming language R and RStudio for reproducibility and repeatability. The OHI Toolbox is stored on the open-source online platform GitHub, which allows for transparency and collaboration and also houses websites to display and communicate methods and results with interactive visualizations. More information can be found at ohi-science.org (currently under a major restructuring and improvement, stay tuned!).
