Deuterium excess record from central Greenland over the last millennium: Hints of a North Atlantic signal during the Little Ice Age
International audience A stacked water isotope record for Summit, central Greenland, has been established covering approximately the last 900 years. Measurements of b•80 and bD in the GRIP deep ice core and the 230-m core, S93, allow the reconstruction of a millennial record of the deuterium excess...

International audience A stacked water isotope record for Summit, central Greenland, has been established covering approximately the last 900 years.

A short period of particularly high values of the Deuterium Excess at the beginning of the fourteenth century may be associated with the medieval warm period (MWP).
