The water-ice in glaciers originally came from the oceans as vapor, later falling as snow and becoming compacted in ice. The method we used was to grow ice from water of known isotope composition. Ice is produced in isotopic equilibrium with the bulk of the water only if the freezing velocity is very small compared to the mixing rate of the water, because otherwise an isotopic gradient is … The LD2012-d18O-Native-age record is the annual mean water isotope (d18O) record for the DSS (Dome Summit South) Law Dome ice core with extensions (e.g. As described in van Ommen et al., Nature Geoscience, 2010) from overlapping ice cores which are dated by comparing multiple chemical species as well as water isotopes. LD2012-d18O-Native-age record spans 2007 A.D. to 174 A.D. The d18O PhD fellow in Ice Core Science. Physics of Ice, Climate and Earth Niels Bohr Institute Faculty of Science.

Boulder, CO USA . Stable isotope ratios of precipitation (“del 18-O” and “del D”) preserved. in ice cores record climate variability across a wide range of spatial and. temporal scales. Ice core dating using stable isotope data Ice consists of water molecules made of atoms that come in versions with slightly different mass, so-called isotopes. Variations in the abundance of the heavy isotopes relative to the most common isotopes can be measured and are found to reflect the temperature variations through the year.
