Effects of Nutrient Enrichment In the Nation’s Estuaries: A Decade of Change

The National Estuarine Eutrophication Assessment (NEEA) is a tool for evaluating both current eutrophic condition and the effectiveness of management actions aimed at reducing eutrophic condition. Eutrophication is caused by excess nutrients and is expressed by symptoms such as increased ...
