    • Ocean circulation and climate at the Eemian and last glacial inception 

      Born, Andreas (Doctoral thesis, 2010-09-24)
      Combining a hierarchy of climate models of varying complexity with marine proxy data, we show that the North Atlantic surface circulation played an important role for the climate of the Eemian and the last glacial inception. ...
