Helicopter-borne Magnetics CASE12
Description
As part of the CASE 12 expedition, geological fieldwork and an aeromagnetic survey were conducted on Ellesmere Island (Canadian Arctic) in the summer of 2011. The helicopter-borne magnetic survey covered the ice-free areas between Vendom Fiord and Strathcona Fiord in the west and the ice-covered mountain ranges of the Inglefield Uplift in the east. With a total flight time of approx. 35 hours, 4200 line kilometres were flown covering a total area of 6000 km². The distance between the individual lines was 2 km, and control profiles perpendicular to the individual lines were flown every 10 km. The aeromagnetic data were recorded by a magnetometer, which was towed approx. 30 m beneath the helicopter.
