How are hydrogen isotopes used to infer polar temperature records?
What will be an ideal response?
Ice cores can be used to estimate past surface temperatures by looking at oxygen or hydrogen isotopes. By analyzing the isotopic composition of frozen water-ice in polar ice cores, we can learn something about the local temperature at the time the ice formed. Warmer water temperatures speed up the evaporation rates of both H2O and HDO. HDO represents water molecules that contain deuterium. Warmer temperatures correspond to a higher HDO content in the snow that falls over Antarctica and in the ice that forms from the snow.
