Dataset Results
As part of the new Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic aqueous geochemical sampling program has been undertaken. A series of terrestrial water samples have been collected and analyzed for major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids (TDS) from relatively pristine glacier ice to hypersaline lake waters.

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.
