A closer look at web tools and sites that boost research and empower Great Lakes communities to secure a healthy environment and economy. 

Monitoring data that used to take months to find and retrieve now takes just minutes with Great Lakes Monitoring. The new web application makes it easy to view and analyze decades of high-quality nutrient, contaminant, and water characteristic data collected by universities and government agencies across the region, including the U.S. EPA Great Lakes National Program Office. 

Interactive maps and menus provide an overview of monitoring locations and allow users to drill down to detailed data profiles for each site and compare specific parameters across multiple sites. From the Explore Trends view, users can see basin-wide patterns for environmental characteristics like phosphorus, chlorophyll a, nitrogen, and mercury.
