Surface water chemistry from Wright and Taylor Valleys Data DOI: https://doi.org/10.15784/602079 Cite as Levy, J., & Pfaff, E. (2026) "Surface water chemistry from Wright and Taylor Valleys" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/602079. Abstract This dataset contains water chemistry data for water tracks and water track-fed ponds from Wright and Taylor Valleys. Active layer water was sampled in 2024-2025 and was analyzed via ion chromatography for major ion analyses and via ion selective electrode for perchlorate concentration. Water activity was measured via an AquaLab 4TE water activity meter.
