DESCRIPTION:Since major outlet glaciers on Greenland started to accelerate
 \, thin and retreat in the early 2000s\, the causes and significance of th
 is change has been debated\, however\, it is widely believed that the comb
 ined effects of surface and submarine melting and loss of buttressing ice 
 mélange play a significant role.  The understanding of the climatic influ
 ence on outlet glacier behaviour is hampered by the short time span for wh
 ich satellite observations of glacier changes and instrumental records of 
 ocean variability exist. The purpose of the SEDIMICE project ('linking sed
 iments with ice sheet retreat') is to extend the glacier and ocean changes
  back in time by analysing sediment cores obtained from the fjords into wh
 ich the outlet glaciers terminate and thus leave sedimentary traces from i
 cebergs and melt water. In this presentation some studies from Sermilik Fj
 ord are presented. The investigated time span covers the last c. 1000 year
 s and thus shed light on oceanographic conditions during and after the LIA
  and the concordant outlet glacier behaviour. With this presentation I wil
 l also take the opportunity to outline some other scientific activities fr
 om the Department of Marine Geology and Glaciology at GEUS.
