Ocean Health Index scores are calculated for each goal separately and then combined to get an overall score on a scale of 0-100. Goal scores are represented by the length of the petals in a flower plot, and the overall score is in the center.
This flower plot shows scores from the 2014 global assessment, where all of Canada’s oceans were assessed together. Incorporating local information, our work will evaluate ocean health at a finer resolution with goals tailored to the region, providing scores for several sub-provincial regions in BC.
The Ocean Health Index framework was published in the scientific journal Nature in 2012 (Halpern et al.). We have since used this framework to complete yearly assessments for each coastal country and territory. We also conduct smaller-scale studies and support independent assessments led by other groups.
