THE RELATIONSHIP AMONG ACCUMULATION RATE, STABLE ISOTOPE RATIO AND SURFACE TEMPERATURE ON THE PLATEAU OF EAST DRONNING MAUD LAND, ANTARCTICA

During traverses in East Dronning Maud Land, which includes Dome Fuji Station (77°19′01″S, 39°42′12″E, elevation 3810m a.s.l.), many glaciological observations have been conducted by the Japanese Antarctic Research Expedition. Among the quantities observed are annual net accumulation (A_<cc> :...

Description
Summary:During traverses in East Dronning Maud Land, which includes Dome Fuji Station (77°19′01″S, 39°42′12″E, elevation 3810m a.s.l.), many glaciological observations have been conducted by the Japanese Antarctic Research Expedition. Among the quantities observed are annual net accumulation (A_<cc> : kg m^<-2>), stable oxygen isotope composition (δ^<18>O : ‰) in the surface snow and mean annual surface temperature distribution. The characteristics of these quantities have been analyzed, and the following equation relating them was obtained : A_<cc>=1.104×10^5exp (0.1462δ^<18>O). In addition, a relation between δ^<18>O and surface temperature has been obtained. These relations suggest a possibility that core chronology and surface temperature variations can be reproduced from the δ^<18>O values in the 2500m-deep ice core drilled at Dome Fuji Station.
