Taking Nitrogen By Storm: Spatial And Temporal Controls On Nitrogen Processing In A Small Reservoir, Eliza Balch Dec 2020

Taking Nitrogen By Storm: Spatial And Temporal Controls On Nitrogen Processing In A Small Reservoir, Eliza Balch

Master's Theses and Capstones

Nitrate inputs pose a threat to aquatic ecosystems, leading to eutrophication, algal blooms, and habitat loss in downstream coastal marine and estuarine habitats. Rivers and streams can attenuate nitrogen between inputs and coastal outputs, moderating ecosystem harm. While nitrogen dynamics in streams and rivers have been studied for decades, less is known about the wetlands through which they flow, namely small reservoirs. Storms can have a large influence on nitrogen processing in reservoirs through hydrologic changes and introduction of new solute sources, but are poorly understood. To understand the spatial and temporal variability of nitrogen processing in a small reservoir, …
