Mercury Concentrations and Isotopic Compositions in Sediment Cores from North American Lakes (Alaska, Minnesota, and Newfoundland)
Mercury isotope measurements were made across nine sediments cores from remote North American lakes to examine changes in the Hg isotope profiles. The lakes spanned regions of Alaska, Minnesota, and Newfoundland as well as a range of temperate to arctic climates. This data describes the natural record of mass dependent (MDF) and mass independent (MIF) Hg isotope fractionation related to depositional changes over time. Mercury isotope measurements were also compared to factors such as latitude, precipitation, watershed size, and approximate age of sediment intervals. The companion article referencing this data set was published in Environmental Science and Technology and can be found at https://doi.org/10.1021/acs.est.0c00579.
