Helicopter-borne Electromagnetics (HEM) Area 109 Hadelner Marsch

BGR conducted an airborne survey in the region of the Hadelner Marsch in cooperation with the GGA Institute (now LIAG) as well as with the water suppliers of Land Hadeln and Wingst. The survey area Hadelner Marsch (2004) is bounded by the river Elbe to the north and by the settlements Bederkesa and Lamstedt to the south. The size of the area is about 700 km². The area was surveyed with 20 flights totalling to 3019 line-km (771,397 survey points). The nominal separation of the 117 ESE-WNW lines and 13 NNE-SSW tie lines was 250 m and 2000 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the five frequencies of the HEM system (0.4 - 140 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of six or twenty model layers).
