Estuarine and Great Lakes (EaGLe)
Coastal Initiative

Visit the EaGLe Research Centers' public websites (external links):



The EaGLe Centers are developing a variety of indicators of coastal environmental condition that best meet the most pressing needs of their particular coast. Indicator types range from the cellular and molecular (bioinformatics) to populations and communities, and from site-based measures of contaminants to remotely sensed indicators using satellites.
