Isotopic Examination of Mercury Methylation and Demethylation Rates in Yellowstone National Park Thermal Features

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 04:18 AM | Dataset Last Updated: February 03, 2022 at 12:00 AM
Data in this data release were obtained for water samples collected under Yellowstone National Park Research Permit YELL-05194 in 2017 through the Integrated Yellowstone Studies Project funded by the Mineral Resources Program. Isotope-spiked incubations were carried out to determine methylation and demethylation potential for Frying Pan spring, Crystal Sister East, Crystal Sister West, and Turbulent Pool, which were selected based on existing data on total mercury and methylmercury concentrations (see companion data release (https://doi.org/10.5066/P9IUY03O). The data represent the experimental conditions of incubation experiments (temperature, time, and experimental spikes) and concentration data associated with each condition.
