Preferred term

deuterium excess  

Definition

  • The δ18O and δD measurements allow us to calculate the deuterium excess, which is defined as follows: d = δD−8*δ18O (Dansgaard, 1964). This second order parameter is mainly dependent on the climatic conditions in the precipitation source regions (Merlivat and Jouzel, 1979). (Adapted from: B. Stenni et al. (2007), The Holocene, 17(7), 1033-1039.)
