Constraining the thermal history of the North American Midcontinent Rift System using carbonate clumped isotopes and organic thermal maturity indices
The Midcontinent Rift System (MRS) is a Late Mesoproterozoic (∼1.1 Ga) sequence of volcanic and sedimentary rocks exposed in the Lake Superior Region of North America. The MRS continues to be the focus of much research due to its economic mineral deposits as well as its archive of Precambrian life and tectonic processes. In order to constrain...
Gallagher, Timothy M.; Sheldon, Nathan D.; Mauk, Jeffrey L.; Petersen, Sierra V.; Gueneli, Nur; Brocks, Jochen J. Sedimentology, sequence-stratigraphy, and geochemical variations in the Mesoproterozoic Nonesuch Formation, northern Wisconsin, USA
We use core descriptions and portable X-ray fluorescence analyses to identify lithofacies and stratigraphic surfaces for the Mesoproterozoic Nonesuch Formation within the Ashland syncline, Wisconsin. We group lithofacies into facies associations and construct a sequence stratigraphic framework based on lithofacies stacking and stratigraphic...

Southwest Wisconsin Groundwater and Geology (SWIGG) study
The fractured bedrock aquifers of southwest Wisconsin are often overlain by shallow soils, so private wells are potentially vulnerable to contamination by nitrate and pathogens from the land surface. The goal of this study is to evaluate the extent and causes of private well water contamination in three southwest Wisconsin counties.
Areas of Concern: Benthos Toxicity at Wisconsin's AOCs
USGS is assessing sediment toxicity at Wisconsin's Sheboygan River and Milwaukee Estuary areas of concern (AOCs) on Lake Michigan. The study will assess if sediment toxicity from polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), selected metals, ammonia, or low dissolved oxygen is present at either acutely toxic or chronically toxic concentrations. Sediment toxicity...

Water Quality Across Regional Stream Networks: The Influence of Land Cover and Land Use, Climate, and Biogeochemical Processing on Spatiotemporal Variance
Land cover and land use (LC/LU), climate, and biogeochemical processing are significant drivers of water quality in streams and rivers over broad scales of space and time. As LC/LU and climate continue to change we can expect changes in water quality. This project seeks to understand the drivers of spatial and temporal variability in water quality across scales using new and existing data to...
Edge-of-field monitoring

Edge-of-field monitoring assesses the quantity and quality of agricultural runoff and evaluates the effectiveness of conservation practices that aim to reduce nutrient loss.
Chemicals of Concern in the Great Lakes Basin
The Great Lakes are an important freshwater source of drinking water, fisheries, and habitat. Chemicals of concern are introduced to the environment by human activities, but resulting ecological consequences are little understood. With federal and University partners, we are characterizing the presence of contaminants and potential effects to fish in Great Lakes tributaries.
Enhance Great Lakes Beach Recreational Water Quality Decision Making
Important questions about beach closures and management remain unanswered in the Great Lakes where over 500 beaches are routinely used along the nearly 11,000 miles of coastline. The economies of coastal areas are dependent on public confidence in the quality of water at the shoreline, and beach managers need reliable science-based information to make beach closure and beach management...
Using optical sensors to detect sewage contamination in the Great Lakes
In the Great Lakes, large volumes of sewage never make it to wastewater treatment plants due to illicit discharges and leaking sewer infrastructure, but contamination can be difficult to detect. This study will define the utility and practicality of using optical sensors to identify the sources and timing of sewage contamination in surface water and storm sewers in real-time field settings....
MMSD Watercourse Corridor Study: Ecological Assessments and Trends
Changes in streams that result from urban development such as loss of stream habitat, inadequate or flashy streamflow, and degraded water quality can adversely affect communities of aquatic organisms. MMSD Watercourse Corridor Study ecological assessments evaluate water quality over time by pairing community assessments of aquatic organisms with chemical assessments using passive samplers.

Exposed Precambrian Bedrock in Part of Dickinson County, Michigan, and Marinette and Florence Counties, Wisconsin
The U.S. Geological Survey conducted a program of bedrock geologic mapping in much of the central and western upper peninsula of Michigan and parts of Wisconsin from the 1940’s until the late 1990’s. Geologic studies in this region are hampered by a scarcity of bedrock exposures because of a nearly continuous blanket of unconsolidated sediments resulting from glaciation of the reg
