Water stable isotope record of ice core NGRIP (top section) ...
A high resolution (0.05 m) water isotopic record (d18O) is available from the NorthGRIP ice core. In this study we look into the water isotope diffusion history as estimated by the spectral characteristics of the d18O time series covering the last 16,000 years. The diffusion of water vapor in the po...
