Helicopter-borne Electromagnetics (HEM) Area 195 Ahlenmoor

BGR conducted an airborne survey in the region of the Ahlenmoor (Lower Saxony) as part of the BGR project D-AERO-Moore. Cunducting tests of their airborne system, the BGR surveys a portion of the Ahlenmoor with the BGR airborne geophysical standard measuring system. The peatland is located about 15 km northeast of the city of Bremerhaven close to Ahlen-Falkenberg. The size of the area is about 15 km². The area was surveyed with 2 flights totalling to 105 line-km (28,258 survey points). The nominal separation of the 16 WNW-ESE lines and 2 NNE-SSW tie lines was 125 m and 2000 m, respectively. The maps display the geophysical parameters apparent resistivity, apparent depth and centroid depth as well as a data quality parameter derived from the HEM data at the six frequencies of the HEM system (0.4 - 130 kHz). Furthermore, vertical slices were derived from layered-earth models (resistivities and thicknesses of six or twenty model layers) for each flightline and also, based on twenty-layer models, 16 horizontal slices at 0 - 100 m below sea level.
