Helicopter-borne Electromagnetics (HEM) Area 081 Cuxhaven
Description
BGR conducted within the project „Pilot study for a detailled airborne geophysical mapping“ (DAGLA) an airborne survey near the city of Cuxhaven. The survey area Cuxhaven (2001) is bounded by the city of Cuxhaven to the north, by the settlements Dorum and Neuenwalde to the south and Altenbruch to the east, and by the North Sea to the west. The size of the area is about 530 km². The area was surveyed with 18 flights totalling to 2427 line-km (615,403 survey points). The nominal separation of the 101 ESE-WNW lines and 32 NNE-SSW tie lines was 250/2250 m (on-shore/off-shore) and 1000/500 m (on-shore/off-shore), 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 - 190 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of six model layers).
