Ocean Health Index scores are calculated for each region for each goal before being combined into an overall Index score for the Main Hawaiian Islands. The four regions are Hawai‘i, Maui Nui, O‘ahu, and Kaua‘i & Ni‘ihau.

Flower plots display preliminary scores, with each petal representing an individual goal. Petal lengths convey the score of the goal, thus longer petals are closer to achieving their target. All scores are on a scale from 0-100, and the center number is the region’s Index score.

For more information on how these scores are calculated see Goals and our technical report.
