O16 and o18 ice cores
Ice cores contain more 16O than ocean water, so ice cores have a lower 18O/ 16O ratio than ocean water or ocean-floor sediments. Water containing the lighter isotope 16O evaporates more readily than 18O in the warmer subtropical regions. ,While there are complexities with the analysis, a simple measurement of the isotopic ratio of 18O in ice cores can be directly related to climate. Ice cores ... ,由 H Riebeek 著作 — Oxygen isotopes in ice cores taken from mountain tops closer to the equator are more difficult to measure since heavy oxygen tends to fall near ... ,Since it is lighter than 18O, 16 ... In addition to the effects of evaporation and precipitation, the amount of ice near the poles affects the delta-O-18 ratio. ,The oxygen 18 O/ 16 O ratio from the Greenland Summit ice cores shows that the rapid temperature increase in the 1920s also took place at the Summit. ,...
