BGR conducted within the project „Airborne geophysical surveys for mapping the shallow subsurface in Germany “ (D-AERO) airborne surveys at the German North Sea coast. The survey area Nordenham (2009/10) is bounded by the Jade Bight to the west and by the river Weser to the east. The size of the area is about 368 km². The area was surveyed with 12 flights totalling to 1569 line-km (435,878 survey points). The nominal separation of the 97 ESE-WNW lines and 11 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 six frequencies of the HEM system (0.4 - 130 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of six model layers).
