United States Department Of Geological Survey

United States Department Of Geological Survey, doing business as Office Of The Coo-Earth System Processes Division, is a U.S. federal government entity and federal agency. As a bureau within the U.S. Department of the Interior, it conducts scientific research and provides impartial information on the health of ecosystems and environment, natural hazards, natural resources, and impacts of climate and land-use change.

This entity has received federal grant sub-awards primarily for conducting research related to sediment sources, phosphorus cycling, and nutrient management in agricultural watersheds, with a focus on the Maumee River Basin. The grants aim to address knowledge gaps that could complicate efforts to reduce phosphorus exports to Lake Erie, such as understanding sediment sources (croplands vs. streambanks), the role of stream and river sediment in long-term phosphorus stocks, and the linkages between upland phosphorus sources and stream processes. The objectives include quantifying sediment source and recency, determining phosphorus sorption-desorption and exchangeability based on sediment source, and examining how sediment source influences phosphorus-dissolved reactive phosphorus exchange during downstream transport. These grants are funded through partnerships with institutions like The Ohio State University and the University of Connecticut. Additionally, the entity has provided sub-award services like thermal infrared cameras, unmanned aerial systems for imagery collection, and related training to support research on groundwater discharge and stream interface sediments in the Farmington River Watershed.
