Nutrient over-enrichment implicated in multiple problems in U.S. waterways

Nutrient Pollution: A Persistent Threat to Waterways

Making Decisions About Safety in US Ports and Waterways

The US Coast Guard (USCG) is charged with maintaining an acceptable level of safety in US ports and waterways. Allocating resources to solve safety problems is difficult because multiple attributes of a port or waterway affect its safety and determine whether a particular safety measure will improve it. We based the ports and waterways safety assessment (PAWSA) model on multiattribute decision ...

Nutrient Enrichment Coupled with Sedimentation Favors Sea Anemones over Corals

Fine sediments, which account for the majority of total fluvial sediment flux, have been suggested to degrade coral reefs on a global scale. Furthermore, sediment impacts can be exacerbated by extreme rainfall events associated with global climate change and anthropogenic nutrient enrichment. We report the findings from a series of mesocosm experiments exploring the effects of short-term sedime...

Erratum: “Nutrient Pollution: A Persistent Threat to Waterways”

Erratum: “Nutrient Pollution: A Persistent Threat to Waterways” The November 2014 News article “Nutrient Pollution: A Persistent Threat to Waterways” [Environ Health Perspect 122:A304–A309; http://dx.doi.org/10.1289/ehp.122-A304] accidentally used the same map to depict both phosphorus and nitrogen pollution in U.S. waterways. In addition, the caption for the phosphorus map incorrectly stated t...

Challenges and Opportunities for Science in Reducing Nutrient Over-enrichment of Coastal Ecosystems

Nutrient over-enrichment has resulted in major changes in the coastal ecosystems of developed nations in Europe, North America, Asia, and Oceania, mostly taking place over the narrow period of 1960 to 1980. Many estuaries and embayments are affected, but the effects of this eutrophication have been also felt over large areas of semi-enclosed seas including the Baltic, North, Adriatic, and Black...
