Phosphorus and nitrogen cycling in streambed and suspended sediment in Bois Brule and Siskiwit Rivers WI, 2021-2023 Data Phosphorus and nitrogen cycling in streambed and suspended sediment in Bois Brule and Siskiwit Rivers WI, 2021-2023 Data
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...
Milwaukee Metropolitan Sewerage District nutrient connections project—In-stream nutrient cycling, 2022 data Milwaukee Metropolitan Sewerage District nutrient connections project—In-stream nutrient cycling, 2022 data
Understanding sediment nutrient dynamics in the Milwaukee River Basin is important for assessing water quality and stream habitat. The Milwaukee River is a major tributary to Lake Michigan that provides clean drinking water for over one million people. Urban and agricultural runoff are linked to elevated loads of phosphorus, nitrogen, and sediment in the river. Excessive nutrients can...
Sediment and nutrient retention in floodplain forest soils related to flood frequency and presence/absence of invasive reed canary grass (Phalaris arundinacea) in the upper Mississippi River Navigation Pool 8 in 2019 Sediment and nutrient retention in floodplain forest soils related to flood frequency and presence/absence of invasive reed canary grass (Phalaris arundinacea) in the upper Mississippi River Navigation Pool 8 in 2019
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...
Fatty acid tissue concentrations of laboratory fed Lampsilis cardium mussels Fatty acid tissue concentrations of laboratory fed Lampsilis cardium mussels
The role of disease in freshwater mussel declines has been largely ignored due to the lack of appropriate diagnostic tools and metabolomic markers of stress. Mussels in this study were either fed a prepared diet or unfed and their condition was assessed with the observed changes in fatty acid content of their tissue. This dataset contains quantitative fatty acid data from nonlethal...
Data from water column and sediment incubations from streams of Duck Creek and Fox River watersheds in Wisconsin, as well as the Fox rivermouth, the Saginaw rivermouth (Lake Huron, MI) and the Maumee rivermouth (Lake Erie, OH) Data from water column and sediment incubations from streams of Duck Creek and Fox River watersheds in Wisconsin, as well as the Fox rivermouth, the Saginaw rivermouth (Lake Huron, MI) and the Maumee rivermouth (Lake Erie, OH)
Nutrient reduction on the landscape scale often focuses on actions that reduce the movement of nitrogen (N) and phosphorus (P) from agricultural lands into streams and rivers. However, processing of N and P in streams and rivers can be substantial and increasing these in-stream processing rates could result in reductions or transformations of nutrients to less labile or less mobile forms...
Great Lakes Restoration Initiative: Nutrient cycling in riverbed sediment in the Maumee River Basin, 2019 and 2021 Data (ver. 2.0, March 2024) Great Lakes Restoration Initiative: Nutrient cycling in riverbed sediment in the Maumee River Basin, 2019 and 2021 Data (ver. 2.0, March 2024)
The Maumee River transports huge loads of nitrogen (N) and phosphorus (P) to Lake Erie. The increased concentrations of N and P are causing eutrophication of the lake, creating hypoxic zones, and contributing to phytoplankton blooms. It is hypothesized that the P loads are a major contributor to harmful algal blooms that occur in the western basin of Lake Erie, particularly in summer...

River-to-lake transitional areas contribute disproportionately to in-lake nutrient loading River-to-lake transitional areas contribute disproportionately to in-lake nutrient loading
River-to-lake transitional areas are biogeochemically active sections of the aquatic continuum that are often understudied compared to their adjoining environments. Internal nutrient loading from river-to-lake transitional areas may be a considerable source of nutrients to lakes and if overlooked disconnect upstream management initiatives from in-lake improvements. To contextualize...

Sediment nutrient dynamics in selected Milwaukee metropolitan area streams, Wisconsin, 2022 Sediment nutrient dynamics in selected Milwaukee metropolitan area streams, Wisconsin, 2022
The U.S. Geological Survey and Milwaukee Metropolitan Sewerage District in Wisconsin have an ongoing partnership to monitor water quality in streams in the Milwaukee metropolitan area and to assess the effects of stream restoration on habitat and water quality. Because sediment nutrient dynamics can improve or further impair water quality, we measured sediment nitrogen and phosphorus

Controls on in-stream nitrogen loss in western Lake Erie tributaries Controls on in-stream nitrogen loss in western Lake Erie tributaries
Management efforts to reduce cyanobacterial harmful algal blooms (cHABs) in the Great Lakes have focused on decreasing tributary inputs of phosphorus (P). Recent research has indicated that reduction of both P and nitrogen (N) can lessen cHABs severity. Microbially mediated N cycling in streambed sediment may reduce N riverine loads, yet little is known about in-stream N processing rates...

Comparison of sediment and water column nutrient processing rates in agricultural streams of contrasting buffer land use Comparison of sediment and water column nutrient processing rates in agricultural streams of contrasting buffer land use
Watershed nutrient management often focuses on actions that reduce the movement of nitrogen (N) and phosphorus (P) from agricultural lands into streams. One area of management focus is the buffer of land adjacent to streams. Wetlands and forests in this buffer can intercept and retain N and P from the landscape. In addition to directly intercepting agricultural nutrients, natural...

Watershed- and reach-scale drivers of phosphorus retention and release by streambed sediment in a western Lake Erie watershed during summer Watershed- and reach-scale drivers of phosphorus retention and release by streambed sediment in a western Lake Erie watershed during summer
Reducing phosphorus (P) concentrations in aquatic ecosystems, is necessary to improve water quality and reduce the occurrence of harmful cyanobacterial algal blooms. Managing P reduction requires information on the role rivers play in P transport from land to downstream water bodies, but we have a poor understanding of when and where river systems are P sources or sinks. During the...

Sediment and nutrient retention on a reconnected floodplain of an Upper Mississippi River tributary, 2013–2018 Sediment and nutrient retention on a reconnected floodplain of an Upper Mississippi River tributary, 2013–2018
The connection of rivers with their floodplains has been greatly reduced in agricultural drainage basins, especially in the Upper Mississippi River Basin. The restriction of the Mississippi River from its floodplain has reduced the sediment trapping and nutrient deposition capabilities of the floodplain, exacerbating water quality problems in the river and in downstream waterbodies. A...
