Lake Superior is historically a nutrient poor lake that does not typically support significant cyanobacterial blooms. However, the lake has been experiencing an increase in blooms in the western portion of the basin recently. The largest blooms documented have occurred after recent major flooding events, indicating that nutrients transported to the lake during these events may be a source for the blooms. This study looks into the combination of streambed sediment-derived nutrient data during base flow conditions and suspended and settled sediment-derived nutrient data from storm events to provide information about nutrient transformation and storage in the river networks of the Bois Brule River and Siskiwit River...

The dataset represents the results of floodplain soil samples collected in Navigation Pool 8 of the upper Mississippi River. The objective of the research was to assess the changes in soil chemistry and nutrient transformation at floodplain forest sites in the presence or absence of invasive reed canarygrass (RCG- Phalaris arundinacea) and determine if the RCG effect was modified by the frequency of inundation of the flood plain soils. The data are structured in a 2x4 factorial experimental design, Factor 1, the presence or absence of RCG in floodplain forest landcover and Factor 2, four levels of flood inundation frequency (0.25-0.32, 0.32-1.35, 1.35-2.35, and 2.35-4 events per year). Soil core samples were collected...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
