Great Lakes Coastal Wetland Monitoring
To assess the biotic condition of all the major coastal wetlands of the Great Lakes, United States and Canadian shorelines.
North Shore Superior Lake and Stream Water Assessment
To collect field and water chemistry data from eight Northern Lakes and Forest (NLF) Ecoregion lakes and three NLF streams during May – September in 2013-14 for the purpose of determining surface water quality.
Amity Creek Restoration Project
Reduce sediment to Amity Creek by improved land cover in riparian areas disturbed by development or legacy impacts, and improved stormwater planning and management tools in two rural townships experiencing continued development pressures, and broader use of stormwater reduction and watershed protection resources available on the regional website www.lakesuperiorstreams.org.
Event-based Stream Sampling in Northeastern Minnesota
Determine pollutant concentrations and annual loads of nutrients and suspended sediments by intensively sampling streams during different hydrologic regimes (base flow, storm events, spring runoff).
GLEI II - Indicator Testing and Refinement
The GLEI-II project will focus on wetland near shore conditions of the Great Lakes, and consist of five tasks: 1) Refine coastal ecosystem indicators from previous monitoring programs through calibration against updated landscape/land use information within the entire Great Lakes basin, 2) test the temporal and geographic integrity of existing Great Lakes indicators. Determine scores for a suite of metrics from sites not sampled previously, and test the applicability of metrics across the Great Lakes basin, including Canada, 3) test and compare analytical techniques to cross-calibrate indicators from concurrent monitoring programs, 4) evaluate indicators for cost-effectiveness, 5) implement a data collection, analysis, and reporting system for recommended indicators as well as a web-based reporting system that integrates landscape/land use information systems, and 6) create a map of baseline conditions for the Great Lakes basin based on historical and current monitoring information.
