Great Lakes Monitoring Results—Comparison of Probability Based and Deterministic Sampling Gridseat Lakes National Program Office (GLNPO) has monitored the open waters of the lakes, annually, since 1983. As part of the U.S. EPA Environmental Monitoring and Assessment Program (EMAP), a pilot study was performed in Lake Michigan to compare the existing GLNPO deterministic sampling grid with the

The Importance of Considering Spatial Attributes in Evaluating Estuarine Habitat Condition: The Soutng multiple measures of water quality, sediment quality, and biological condition. Sampling was subsequently expanded to include components required for the National Coastal Assessment (Coastal 2000) Program. Habitats are classified as either “tidal creeks” (< 100 meters in width) or larger “open wa
