Oxygen isotope analyses of surface snow layers have been carried out in Enderby Land-East Queen Maud Land, East Antarctica. The δ^<18>O values decrease with various parameters including elevation (E : m), distance from the coast (L : km) : [δ^<18>O(‰)=-0.0069E-0.0126L-18.5], and in particular with mean annual surface temperatures (T : ℃), according to a good linear relationship [δ^<18>O(‰)=0.834T-8.7] in the temperature range from -20 to -55℃. The relationship with temperature is similar to that derived from a simple model in which an air mass is progressively cooled under Rayleigh conditions as it moves toward the inland plateau. This also suggests that δ^<18>O values are very closely related to condensation temperature at the top of the inversion layer where snowfall precipitation is formed. |
