Hydro-Chemistry of Gokyo Valley, Sagarmatha (Everest) National Park, Nepal

A study of the hydro-chemistry of Gokyo Valley, Sagarmatha (Everest) National Park, Nepal, reveals that ion concentrations in running waters—particularly calcium (Ca²⁺), magnesium (Mg²⁺), and total silica—are primarily influenced by weathering processes, glacier characteristics, and snow cover dynamics rather than elevation alone. The research found weak correlations between these ions' concentrations and elevation gradient, suggesting complex interactions shaping water chemistry in the valley. Sampling during a drier period with low atmospheric acid input likely contributed to lower-than-expected ion levels compared to previous studies. This baseline inventory provides critical insights into the hydro-chemical dynamics of this pristine high-altitude environment.
