In the summer of 2010 one group (5 persons/1 month) worked in the interior of the extensively ramified Nuuk Fjord system. Five lakes were cored. Some of these were “threshold lakes”, which were cored for their signal of nearby glacier retreat and advance. The three others were cored for their Holocene organic sediments as part of our research into sedDNA and, combined with geochemical parameters, its use as climatic and environmental proxy. Among these lakes was Johs Iversen Sø, one of the most extensively investigated lakes in Greenland. The field work also comprised a revision of the deglaciation history of this area, using exposure samples from large valley systems in this area of alpine and heavily dissected topography, and OSL dating of large deglacial sediment accumulations. Another group (2 persons/3 weeks) worked along the same lines in Sermilik Fjord in south-east Greenland, – coring 2 lakes and collecting exposure samples. However, here a main activity was to make photogrammetry of glacier fronts, which were investigated during the past Geophysical years in 1933 and 1956. Finally, a suite of exposure samples was collected in the Upernavik area (1 person/1 week) in connection with ongoing geophysical work. For 2011 a roster of scattered RINK-activities is planned: a continuation of field work in the Sermilik area, south-east Greenland (3 persons/2 weeks), lake coring at Jakobshavn in connection with ongoing geophysical investigations (1 person/1week), lake coring and remote sensing of types of periglacial terrain surfaces on Disko island (2 persons/2 weeks) in connection with ongoing studies of permafrost and a student course, and, finally, glacier-photogrammetry in the Upernavik area in connection with ongoing geophysical studies (1 person/1 week).
