Helicopter-borne Radiometrics (HRD) Area 196 Gnarrenburg

BGR conducted an airborne survey in the region of Gnarrenburg (Lower Saxony) as part of the BGR project D-AERO-Moore. This project is a study to survey the mires near Gnarrenburg with the BGR airborne geophysical standard measuring system. The peatland is located about 30 km northeast of the city of Bremen between Bremervörde and Worpswede . The size of the area is about 173 km². The area was surveyed with 6 flights totalling to 778 line-km (20,789 survey points). The nominal separation of the 62 WNW-ESE lines and 6 NNE-SSW tie lines was 300 m and 1500 m, respectively. In addition, 33 NNO-SSW lines at 100 m line separation were flown. The maps display the total count, the (equivalent) content of potassium, uranium and thorium as well as the exposure rate at ground.
