Helicopter-borne Electromagnetics (HEM) Area 087 Bremerhaven
Description
BGR conducted within the project „Pilot study for a detailled airborne geophysical mapping“ (DAGLA) an airborne survey near the city of Bremerhaven. The survey area Bremerhaven (2001) is bounded by the settlements Dorum and Neuenwalde to the north, Bederkesa and Wehdel to the east, Lunestedt and Stotel to the south, and by the river Weser and the North Sea to the west. The size of the area is about 550 km². The area was surveyed with 13 flights totalling to 2227 line-km (588,067 survey points). The nominal separation of the 107 ESE-WNW lines and 26 NNE-SSW tie lines was 250 m and 1000 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 - 190 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of five model layers).
