Short summary
The first comprehensive study of a set of 76 firn cores in Dronning Maud Land was carried out. The δ18O of both the plateau and the ice shelf cores exhibit a slight positive trend over the second half of the 20th century. The SMB has a negative trend in the ice shelf cores, but increases on the plateau. Comparison with meteorological data revealed that for the ice shelf regions, atmospheric dynamic effects are more important, while on the plateau, thermodynamic effects predominate.
