Great Lakes Science Center
Welcome! The Great Lakes Science Center (GLSC) is part of the Midcontinent Region of the USGS, DOI Regions 3 and 5. Our scientists work in the Great Lakes region and other parts of the country to meet the nation’s need for scientific information used by resource managers to restore, enhance, manage, and protect the living resources and habitats in the Great Lakes basin.

Egg size scales negatively with system size in a periodic fish species
Optimal egg size theory implies that female organisms balance between fecundity and individual offspring investment according to their environment. Past interspecific studies suggest that fishes in large marine systems generally produce smaller eggs than those in small freshwater systems. We tested whether intraspecific egg size variation reflected a similar pattern by comparing egg size among yel
An assessment of N, P, Fe, Zn, Ni and Mo limitation on suspended nutrient diffusing substrates in nearshore areas of Lake Michigan and Lake Erie
In large lakes, metal availability sometimes limits the acquisition of nutrients (nitrogen, N and phosphorus, P) in offshore waters that are relatively isolated from tributaries and sediments. We hypothesize that metals may also be important within harmful algal blooms (HABs). HABs occur where nutrient loads are elevated, but bioassays often indicate that phytoplankton in HABs are N or P limited.

Long-term Monitoring of Great Lakes Coastal Wetlands and Contributions to the Coastal Wetland Monitoring Program
The Coastal Wetland Monitoring Program (CWMP) is an EPA-led program to monitor the health of all Great Lakes coastal wetlands larger than four hectares. USGS scientists are working with Principal Investigators from many State and academic institutions to conduct data collection, implement standardized sampling protocols, analyze multiparameter data, and communicate results to the public.
Invasive Phragmites Science: Using Microbial Interactions to Foster the Restoration of Great Lakes Wetlands
The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine (1) if microbes (i.e., fungi and bacteria) that live within and around Phragmites are enabling the...
Restoring Wetland Habitat and Function at the Shiawassee National Wildlife Refuge
Hydrologic connectivity is essential to maintaining coastal wetland services and functionality. Impounded wetlands often do not provide essential services such as flood mitigation and nutrient retention, nor can they be utilized as spawning and nursery habitat by important Great Lakes fishes. The Shiawassee National Wildlife Refuge manages hundreds of acres of historical coastal wetland habitat...
