Road Salt Runoff - Impact on Macroinvertebrates and Water Quality
… impacts road salt application may have on river chemistry and its macroinvertebrate community composition. Additionally, the potential of molecular method, environmental DNA (eDNA), was investigated by comparing the results from kick sampling to those of the eDNA. The results from the study …

Contact metamorphism of the Mancos shale: impacts on solute release and weatherability in the East River Valley, Gothic, CO
… metamorphism of Mancos shale bedrock in the East River provides a natural test bed to investigate the role of underlying geology on weathering susceptibility, solute release rates and changing river chemistry in metamorphosed and unmetamorphosed sections of the Mancos shale. To analyze the …

Evolution of chemical composition along river drainage networks
<p>Surface water chemistry from a tropical and temperate rivers system was studied in order to understand the controls on longitudinal variation of stream chemistry. In the Rio Icacos-Blanco system in Puerto Rico, I examined changes in stream chemistry associated with a change in bedrock …

Impacts of Carbonate Mineral Weathering on Hydrochemistry of the Upper Green River Basin, Kentucky
<p>Kentucky’s Upper Green River Basin has received significant attention due to the area’s high biodiversity and spectacular karst development. While carbonate bedrock is present throughout the watershed, it is more extensive and homogenous along the river between Greensburg and Munfordville than …

Adsorption–Desorption Reactions in the Weathering Zone: Implications for Silicate Weathering & the Carbon Cycle
… reaction products (solutes) transported by large rivers. However, this approach may overlook ions chemically bound to the surfaces of sediments, which can be significant in highly erosive regions. To better understand the contribution of the adsorbed phase to chemical weathering budgets, a …

Silicate weathering in the Himalayas: Constraints from the Li isotopic composition of river systems
… with cations, thereby controlling both seawater chemistry and climate. The rate of CO2 consumption is closely linked to the rate of CO2 outgassing from the planetary interior, providing a negative feedback loop essential to maintaining an equable climate on Earth. Reconstruction of past global …
