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


What Does This Score Mean?

Clean Waters measures the degree to which waters are polluted by eutrophication (excess nutrients), chemicals, pathogens, and trash. The reference point is zero pollution.

This goal score is higher when the pollution of estuarine, coastal, and open ocean waters is minimized. The goal score is lower when there are high levels of pollutants.

Current Score

The current score indicates that the ocean may have lower levels of pollutants than anticipated, but there are still large opportunities for improvement. Reducing the inflow of excessive nutrients and levels of chemicals, pathogens and trash requires remedial actions at every level of government as well as adjustments to behavior on an individual basis.

How Is It Measured?

Each goal is evaluated on the basis of four dimensions
Present Status

Present Status is a goal's current value (based on the most recent available data) compared to a reference point.

Trend

Trend is the average percent change in the present status for the most recent 5 years of data.

Pressures

Pressures are the sum of the ecological and social pressures that negatively affect scores for a goal.

Resilience

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.


Pressures

Pressures are human-caused stressors that influence both ecological and social systems, negatively affecting the ability of a goal to deliver its benefits to people.


Status

Status refers to the current value of a goal relative to its goal-specific reference point. The reference point is the best condition for a goal that can reasonably be achieved; it is a target to aim for when taking actions to improve ocean health.


Resilience

Resilience refers to the social, institutional, and ecological factors that positively affect the ability of a goal to deliver its benefits to people.
