Aeromagnetic survey in central West Greenland: project Aeromag 2001
The series of government-funded geophysical surveys in Greenland was continued during the spring and summer of 2001 with a regional aeromagnetic survey north of Uummannaq, project Aeromag 2001 (Fig. 1). The survey added about 70 000 line kilometres of high-quality magnetic measurements to the existing database of modern airborne geophysical data from Greenland. This database includes both regional high-resolution aeromagnetic surveys and detailed surveys with combined electromagnetic and magnetic airborne measurements.High-quality magnetic data are now available for all the ice-free area of West and South Greenland from the southern tip of Greenland to Upernavik Kujalleq/Søndre Upernavik (Fig. 1). The total surveyed area with highresolution magnetic data is 250 000 km2 and corresponds to a total of 515 000 line kilometres. Detailed surveys with combined electromagnetic and magnetic measurements were carried out in six separate surveys in selected areas of high mineral potential during project AEM Greenland 1994–1998, a total of 75 000 line kilometres. Descriptions of the previous surveys can be found in Thorning (1993), Stemp & Thorning (1995), Thorning & Stemp (1996, 1998), Stemp (1997), Rasmussen & Thorning (1999), Rasmussen & van Gool (2000) and Rasmussen et al. (2001).
