Rapid oscillations in Vostok and GRIP ice cores
International audience We investigate the spectral properties of climatic times series derived from two recent ice cores in Greenland and East Antarctica. We find that the signals behave in a similar way in the high frequency part of their spectra. The rapid oscillations found in the GRIP ice core w...
