Welcome to the Great Lakes Coastal Wetlands online explorer, provided by Michigan Tech Research Institute (MTRI). Through a binational collaborative project between Canada and the United States, the team has been working to better measure and map coastal wetland features and hydrologic changes through time at fine resolution. Several remote sensing derived products have been developed for monitoring wetland type, extent and inundation of Great Lakes coastal wetlands.
By definition, coastal wetlands are hydrologically connected to the Great Lakes. By nature, coastal wetlands are therefore affected by inter and intra-annual fluctuating lake levels causing wetlands to shift shoreward in high water conditions and lakeward in low water conditions. Stressors, such as nutrient loading, pollutants and land development, also influence the wetland condition, type and extent. Geospatial remote sensing products are being developed to capture the temporal changes in these dynamic systems.
