The Iowa Nutrient Research Center's Fall 2024 Seminar Series will focus on recent trends in surface and groundwater nutrients across the US, highlighting the status of nutrients and water quality around the country, including in Nebraska, the Mississippi River, the Chesapeake Bay and Lake Erie.
Long-Term Nutrient Trends from the Mississippi River Basin into the Gulf
Presenter: Lori Sprague, national program manager, Integrated Water Availability Assessments (IWAAs) Program, U.S. Geological Survey
The USGS has monitored nutrients in the Mississippi River since the 1970’s. This long-term observational record is updated with new monitoring data annually, which is used to both forecast and understand the size of the hypoxic zone in the Gulf each year as well as to track progress toward nutrient reduction goals set by the interagency Mississippi River/Gulf of Mexico Hypoxia Task Force.
This presentation will delve into long-term trend assessment methods, results and possible causes.
