This dataset shows concentrations of lithium, sodium, potassium, magnesium, calcium, iron, chlorine, bromine, silicon, fluorine, sulfate, and hydrogen ions found in various streams of the McMurdo Dry Valleys. Although the majority of the streams in the study are found in Taylor Valley, data has also been collected from streams in the nearby Miers, Alph, Wright, Pearse, Garwood, and Victoria Valleys. An extensive network of gauging stations was set up throughout these valleys to monitor the stream hydrology. While collecting hydrology data, stream water samples to be used for chemical analysis are also gathered. Sample locations for stream chemistry data thus coincides with those for hydrology samples.
Locations also remain consistent from season to season.
Specific latitudes and longitudes for each stream gauge can be found in the stream gauge locations table of this web site. Welch, K., W.B. Lyons, J.C. Priscu, R. Edwards, D.M. McKnight, H.
