Unraveling Isotope Fractionation: Decoding Earth’s Geological History
IsotopicIsotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Isotope fractionation occurs when isotopes of the same element are separated by physical or chemical processes. Isotope fractionation is an important tool in the study of Earth’s geologic history. By studying the ratio of isotopes in

Isotopic Verification Unveils Accuracy of Ice Core Temperature Reconstructions
IsotopicIce cores are long cylinders of ice drilled from glaciers and ice sheets that provide a record of past climate change. One of the most important climate variables that can be reconstructed from ice cores is temperature. This is done by measuring the isotopic composition of the ice, which reflects the temperature at the time
