Upper Midwest Environmental Sciences Center


Our Upper Midwest Environmental Sciences Center's priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices. If you need additional assistance, please contact the UMESC Director Mark Gaikowski, (mgaikowski@usgs.gov), or Randy Hines (rkhines@usgs.gov).

Use of Robotic DNA Samplers That Can Rapidly Detect Invasive Aquatic Species

USGS researchers and their collaborators demonstrated the efficacy of using robotic environmental DNA samplers for bio surveillance in freshwater systems, showing that samples collected, processed, and preserved by robotic sampler detect organism DNA in the environment at rates comparable to those collected traditionally by human technicians.

Microplastics in the Delaware River, northeastern United States

Microplastics are a contaminant of increasing concern in aquatic environments. Our understanding of microplastics in freshwater environments has increased dramatically over the past decade, but we still lack information on microplastic occurrence and biological uptake in National Park Service (NPS) waters. During 2015–19, the U.S. Geological...

Monitoring wetland water quality related to livestock grazing in amphibian habitats

Land use alteration such as livestock grazing can affect water quality in habitats of at-risk wildlife species. Data from managed wetlands are needed to understand levels of exposure for aquatic life stages and monitor grazing-related changes afield. We quantified spatial and temporal variation in water quality in wetlands occupied by threatened...

Assessment of NMR logging for estimating hydraulic conductivity in glacial aquifers

Glacial aquifers are an important source of groundwater in the United States and require accurate characterization to make informed management decisions. One parameter that is crucial for understanding the movement of groundwater is hydraulic conductivity, K. Nuclear magnetic resonance (NMR) logging measures the NMR response associated with...
