*The estimate of a goal’s likely near-term future status is a function
of four dimensions: Status, Trend, Pressure, and Resilience.



An Index Organized by
10 Public Goals

Each goal has an optimum reference point determined by a team of experts. The target is considered attainable and is more sustainable than the current conditions. A score of 100 meets the target. The Ocean Health Index was started in 2012 and reports new scores annually. Roll over the chart to learn more about each goal.

Food
Provision

Seafood is a fundamental component of our diet, contributing to the basic protein needs of nearly half of the world’s population. This goal measures the amount of seafood harvested primarily for human consumption and how sustainable it is.

Food Provision is divided into two sub-goals: Wild-caught commercial seafood and Mariculture, or ocean-farmed seafood.

Artisanal Fishing
Opportunities

Local fishing provides jobs and feeds families in communities around the world, especially in developing nations. This goal measures the degree to which a nation permits or encorages artisanal fishing compared to the demand for fishing opportunities, and in the future will include the sustainability of artisanal fishing practices.

Natural
Products

From seashells and sponges to aquarium specimens, non-food ocean resources support local economies and international trade. This goal measures the amount and sustainability of harvest levels pertaining to marine ornamental fish specimens for aquariums, coral products, fish oil, seaweed, sponges, and shells.

Carbon
Storage

The ocean and the coastal plant habitats fringing its shores play a major role in slowing global warming by absorbing and storing atmospheric carbon (CO2). This goal measures the current condition or area of coastal plant habitat coverage relative that in ~1980.

Coastal
Protection

Coral reefs, mangroves, seagrasses, salt marshes, and sea ice act as natural buffers against incoming waves, protecting people from storm damage, flooding, and erosion. This goal assesses the amount of protection these coastal habitats provide by measuring the current area they cover relative to the area they covered in the recent past.

Coastal Livelihoods
& Economies

The ocean is an important source of jobs and revenue for individuals, businesses, and communities worldwide. This goal measures a country’s ability to maintain coastal livelihoods and economies in ten marine sectors, from shipping and transportation to wave and tidal energy.

This goal is divided into two sub-goals: Livelihoods, and Economies.

Tourism
& Recreation

Whether it's a day at the beach, snorkeling on reefs, or a weeklong cruise, people enjoy visiting coastal areas and taking part in the many recreational activities that they offer. This goal evaluates the attraction of (priced and un-priced) coastal and marine activities by measuring the number and length of international tourist visits, and sustainability as indicated by tourist density.

Sense of
Place

People derive a sense of cultural identity from coastal and marine areas. For people living both near to and far from the ocean, knowing that particular species or places exist provides important cultural, spiritual, and personal value. Sense of Place measures the condition of culturally iconic species and the percentage of protected places within a country.

Sense of Place is divided into two sub-goals:
Iconic Species, and Special Places

Clean
Waters

Waters contaminated by pollutants have negatively impact human health, livelihoods, and recreational opportunities, as well as the health of marine wildlife and ecosystems. This goal measures the degree to which waters are polluted by eutrophication (excess nutrients mostly from fertilizers or sewage), chemicals, pathogens, and trash.

Biodiversity


An ocean filled with diverse species and flourishing habitats can produce food, jobs, recreation, coastal protection, and other benefits now and in the future. This goal measures the conservation status of marine species and the condition of key habitats that support species richness and diversity.

Biodiversity is divided into two sub-goals: Species and Habitats.

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, terr
