An Index Organized by
10 Public Goals
Evaluated globally and by country, these 10 public goals
measure benefits that a healthy ocean provides to people.
All scores range from 0 to 100.
Overall and Goal Scores by EEZ
- Food Provision
- Artisanal Fishing Opportunities
- Natural Products
- Carbon Storage
- Coastal Protection
- Coastal Livelihoods & Economies
- Tourism & Recreation
- Sense of Place
- Clean Waters
The OHI results are shown on the exclusive economic zone (EEZ) of each coastal country, an area that extends 200 nautical miles (370 KM) offshore from the country’s coast. For countries with multiple and separate coastlines, EEZs were grouped based on country, latitude, habitation, and ocean basin.
When a goal is not relevant to a specific country, no value (N/A) is shown and that goal is not included in calculation of the country’s overall Index score.
Results were not calculated for the high seas (international waters)
or for Antarctica.
Due to standardized usage in interactive mapping, the Web Mercator projection has been selected to display Index data. The advantage of Mercator Projection is that it is the only projection to show true compass direction, so a line drawn Southeast on the map will also be Southeast on the earth’s surface. The disadvantage is that countries and areas nearer to the poles appear disproportionately large e.g.Northern Hemisphere countries in Europe and North America appear larger than they actually are.
The political and geographic designations shown on this map do not imply the expression of any opinion on behalf of the Ocean Health Index concerning the legal status or delineation of the frontiers of any country, territory or area.
Country Scores Breakdown
Each goal is evaluated on the basis of four dimensions.
Present Status is a goal's current value (based on the most recent available data) compared to a reference point.
Trend is the average percent change in the present status for the most recent 5 years of data.
Pressures are the sum of the ecological and social pressures that negatively affect scores for a goal.
Resilience is the sum of the ecological factors and social initiatives (policies, laws, etc) that can positively affect scores for a goal by reducing or eliminating pressures.
