The Moorhead Environmental Complex — Sharing Stroud Science Starts Here: The board of directors cut the ribbon on a new building for environmental education and public outreach that models sustainable practices for managing water.

Dynamics of Organic Particles in River Ecosystems

800 532 Stroud Water Research Center

Suspended organic particles are important to river food webs and in the transfer of organic carbon from land to ocean. In an experiment conducted in Stroud Water Research Center’s streamside…

Hydrologic Regulation of Dissolved Organic Matter Biogeochemistry From Forests Through River Networks

800 532 Stroud Water Research Center

This collaborative proposal will generate the mathematical models that simulate stream flow in White Clay Creek and the movement of water carrying dissolved organic carbon from soils to the stream.…

The Application of Scaling Rules to Energy Flow in Stream Ecosystems

800 532 Stroud Water Research Center

Scientists have grown young deciduous trees in an atmosphere enriched with the stable isotope of carbon so as to follow the fate of those organic molecules in small laboratory reactors,…
