The Eirik Drift has been documenting the sedimentation near southeast Greenland since the Miocene. This sediment drift forms an important archive for the depositional processes in this region, which have been shaped by the Western Boundary Undercurrent (WBUC), the Greenland ice sheet and the material input from the Labrador Sea/Davis Strait. The incorporation of high resolution seismic reflection data acquired during RV Maria S. Merian cruise MSM 12/2 in June/July 2009 with geologic information from ODP and IODP sites (ODP Leg 105 and IODP Expedition 303) will lead to information on the development of the WBUC as well as the dimensions and expansion/retreat of the Greenland ice sheet and a much clearer understanding of the evolution of the climate southwest of Greenland. A comparison with sediment drifts from the southern hemisphere will further allow conclusions regarding global climate variations.

自中新世以来，埃里克漂移一直在记录格陵兰岛东南部附近的沉积。西边界潜流（WBUC）、格陵兰冰盖和拉布拉多海/戴维斯海峡的物质输入形成了该地区沉积过程的重要档案。将2009年6月/ 7月Maria S. Merian号巡航MSM 12/2期间获得的高分辨率地震反射数据与ODP和IODP站点（ODP Leg 105和IODP Expedition 303）的地质信息结合起来，将获得有关WBUC发展的信息，以及格陵兰冰盖的大小和扩张/退缩的信息，并更清楚地了解格陵兰西南气候的演变。与南半球沉积物漂移的比较将进一步得出关于全球气候变化的结论。
