    • Chemical and isotopic composition of gas, water, and solids from the 2019-2020 water lake in Halema’uma’u Crater, Kīlauea Volcano, Hawaii: Water Isotopes

    Metadata Updated: July 6, 2024

    Water samples for Oxygen-18 and deuterium isotope determinations were stored unfiltered in 15 ml glass bottles and analyzed at the USGS laboratories in Reston, Virginia. Analysis of oxygen isotopes was according to the methods of Epstein and Mayeda [1953] with a precision of ±0.1‰, and the hydrogen isotopes were analyzed according to the method described in Kendall and Coplen [1985] and Coplen et al. [1991] with a precision of ±1.5‰. Ratios are reported relative to VSMOW. References: Coplen, T. B., J. D. Wildman, and J.
