The catchment for the retreating Greenlandic ice cap is an ideal site to get further insight in the mechanisms behind regime shifts, the duration between shifts and the resilience towards the changes, since it is possible along the transect form the ice edge, to find areas of different ages. By analyzing physical-chemical variables and biological remains in different sediment layers from deep lakes we can evaluate the response of the lakes to former cold and warm periods through the Holocene, where the ice expanded and retreated.

The area in the bottom of the Godthåbsfjord must be compared to the area near the Ilulissat-glacier, which was investigated in 2012. Furthermore results from these two areas will be compared with future investigated areas to be sampled in areas in North Greenland.
