Summary

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.

Purpose

This dataset was collected to determine the rates of mercury transformation, methylation and demethylation across different Yellowstone National Park thermal features. Understanding the speciation and methylation rates of mercury within the park allows for a better understanding of formation and transport of methylmercury, the form that actively bioaccumulates in wildlife.
