Description of Work U. S. Geological Survey (USGS) will identify through this project significant sources and impacts of historical and newly emerging toxics to the Great Lakes ecosystem through broad surveillance as well as laboratory and field research of tree swallows and other bird species. USGS scientists will determine the amount of exposure to and the effects of historical and emerging contaminants in Great Lakes food chains. The data will inform regulators and provide guidance on removal of Beneficial Use Impairments at Area of Concern sites around the Great Lakes. Work supported under this project is quantifying exposure to, and effects of, both historical and emerging contaminants on Great Lakes food chains...
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS). Aerial images of Pools 1-13 Upper Mississippi River System and Pools, Alton-Marseilles, Illinois River were collected in color infrared (CIR) in August of 2010 at 8”/pixel and 16”/pixel respectively using a mapping-grade Applanix DSS 439 digital aerial camera. In August 2011, CIR aerial images of Pools 14-Open River South, Upper Mississippi River and Pools Dresden-Lockport, Illinois River were collected at 16”/pixel with the same camera. The CIR aerial images were interpreted and automated using a 31-class LTRM vegetation classification....

The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:15,000-scale color infrared aerial photos. These data have been used to create a variety of products, one of which is a data set used to classify aquatic areas. The 1989 and 1991 aquatic areas data sets were created by first generalizing the available land cover/use data into a land/water data set, then reinterpreting the aerial photography within the areas classified as water to determine the type of aquatic area. The geographic extent of the UMRS is the Mississippi River floodplain from Cairo, IL to Minneapolis, MN and the Illinois...

c) We examined effects of flooding on supply rates of 14 nutrients in floodplain areas invaded by Phalaris arundinacea (reed canarygrass), areas restored to young successional forests (browsed by white-tailed deer and unbrowsed), and remnant mature forests in the Upper Mississippi River floodplain. Plant Root Simulator ion-exchange probes were deployed for four separate 28-day periods. The first deployment occurred during flooded conditions, while the three subsequent deployments were conducted during progressively drier periods. Time after flooding corresponded with increases in NO3--N, K+ and Zn+2, decreases in H2PO4--P, Fe+3, Mn+2, and B(OH)4-B, a decrease followed by an increase in NH4+-N, Ca+2, Mg+2 and Al+3,...

The shapefiles depict the valley bottom areas over which HEC-RAS model results were summarized. Valley bottoms were manually delineated in ArcMap by visually interpreting LIDAR terrain models and aerial imagery. Substantial changes in elevation, curvature, and slope were interpreted within the context of their position within the study reach to be channel banks and valley walls. Such areas were excluded from the valley bottom delineation.

Hydraulic connection between channels and floodplains (“connectivity”) is a fundamental determinant of ecosystem function in large floodplain rivers. Factors controlling material processing in these rivers depend not only on the degree of connectivity but also on the sediment conditions, nutrient loads and source. Nutrient cycling in the nutrient-rich upper Mississippi River (MISS) is relatively well studied, while that of less eutrophic tributaries is not (e.g., St Croix River; SACN). We examined components of nitrogen cycling in two floodplain rivers of contrasting nutrient enrichment and catchment land-use to test the hypothesis that N-cycling rates will be greater in the MISS with elevated nutrient-loads and...

Hydroacoustic (sonar) data were collected for the Mississippi, St. Croix, and Minnesota Rivers for the development of high-resolution bathymetry and sidescan imagery. Small areas containing priority mussel habitat had additional collection efforts to map water velocities and bottom composition. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. This information is highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution. The collaborative effort was funded by the Legislative-Citizen Commission on Minnesota Resources (LCCMR) Environment and Natural...

The concentrations of selected metals (mercury [Hg], lead, cadmium, selenium [Se], and aluminum) were determined in common loon (Gavia immer) blood samples collected from across a broad area of Minnesota. The observed pattern of loon Hg exposure was related to Hg concentrations in a standardized 12-cm whole organism yellow perch (Perca flavescens), based on fish Hg records from lakes throughout Minnesota, using the U.S. Geological Survey National Descriptive Model for Mercury in Fish.

Tree swallows, Tachycineta bicolor, were sampled across the Great Lakes basin in 2010-2015 to provide a system-wide assessment of current exposure to organic contaminants. These results provide information identified as critical by land managers and regulators to assess the ‘Bird or Animal Deformity or Reproductive Problems’ Beneficial Use Impairment. Eggs were collected from 69 sites across all five Great Lakes, including 27 Areas of Concern (AOCs), some with multiple sites, and ten sites not listed as an AOC. Concentrations of organic contaminants in eggs were quantified and compared to background and reproductive effect thresholds. Approximately one-third of the AOCs had geometric mean concentrations of total...

Coastal and estuarian wetlands in the Great Lakes Basin are increasingly impacted by habitat degradation, invasive species, and most recently (late 2010's), increased water levels. These wetlands act as an important buffer between the open lake and the near-shore areas, as key areas for nutrient cycling, as critical nurseries for many species of lake fish, and as habitat for numerous species of concern. Understanding how the cover and composition of these wetlands has changed over time is critical to making informed management decisions. By using both historical documents and imagery, multiple historic maps of wetland coverage were created in GIS to compare over time and to current maps and imagery of these critical...

High-resolution digital aerial imagery was collected on August 23 and 24, 2018, with an 80-megapixel Phase One iXU-R 180 natural color aerial camera co-mounted with a Phase One iXU-RS 160 achromatic aerial camera. Software co-registers the simultaneously collected images to create 4-band imagery that can be displayed in either true color (RGB) or color-infrared (CIR) format. The camera system is connected to the plane's positioning and orientation system and precise metadata was generated for each exposure. This imagery was intended to be used as a base layer for object-based image analysis (OBIA) to map aquatic vegetation in western Lake Erie.

This shapefile describes the outputs from the application of a decision support tool (Rohweder and others 2015) used to assist the Minnesota Valley Wetland Management District make thoughtful and strategic choices about where to spend its limited management resources. It incorporates landscape and management unit features to identify which Waterfowl Production Areas have the greatest biological potential with respect to priority resources and habitats. The district can use this information to prioritize and target management, which will help with development of annual habitat plans. This shapefile contains the relevant input criteria attributes used in the development of station objective models.

Description of Work The GLRI Rivermouths Project (template 82) is designed to enhance our understanding of how rivermouths function at both regional and local scales by 1) developing a rivermouth classification system, based on a broad scale database covering all Great Lakes rivermouths (>2000); 2) creating a science-based understanding of how the ecological structure and function of rivermouths are linked both to the landscapes they drain and to the Lakes with which they mix; and 3) increasing the public and scientific profile of these ecosystems by connecting researchers and natural resource managers through a collaborative dialog. The long-term goal is to provide enhanced guidance for restoration and rehabilitation...
