Title
Trends in Surface and Groundwater Nutrients Across the U.S. - December 2024

Agricultural Phosphorus and Lake Erie
Presenter: Nathan Manning, Research Scientist, National Center for Water Quality Research, Heidelberg, University

This presentation was part of the Iowa Nutrient Research Center's Fall 2024 Seminar Series, focusing on recent trends in surface and groundwater nutrients across the US and highlighting the status of nutrients and water quality around the country, including in Nebraska, the Mississippi River, the Chesapeake Bay and Lake Erie. 

Nutrient and Sediment Loads Measured from the Chesapeake Bay River Input Monitoring Network - November 2024

Presenter: Jimmy Webber, hydrologist, U.S. Geological Survey

Nutrient and sediment loads are changing over time in the Chesapeake Bay watershed. This presentation will describe how the USGS uses a river monitoring network to assess these water-quality trends. Recent load and trend results from this monitoring network will be presented and discussed in context with Chesapeake Bay water-quality goals.

Iowa Nutrient Researcher Directory

The Iowa Nutrient Researcher Directory is a web directory designed to guide visitors to diverse types of research projects to reduce nitrogen and phosphorus in Iowa's waters and the researchers leading those projects. This short video about the directory features four scientists working in diverse types of projects with Iowa State University, the University of Iowa and University of Northern Iowa whose work has received support from the Iowa Nutrient Research Center.
