Physical and chemical characteristics of stream-associated snow patches in Fryxell Basin, McMurdo Dry Valleys, Antarctica during the 2021-2022 austral summer

Summary

Abstract: 

Snow patches within and adjacent to stream channels in the Fryxell Basin of Taylor Valley, Antarctica were sampled during the 2021-2022 austral summer as part of the McMurdo Dry Valleys Long Term Ecological Research program. This data package includes snow pit measurements (snow temperature, depth, density, and water equivalent) as well as chemical characteristics of snow samples that were analyzed for nutrient, cation, and anion concentrations.
