Helicopter-borne Electromagnetics (HEM) Area 130 Borkum

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 of the East-Frisian island of Borkum (2008) is bounded by the Westerems close to the Dutch-German border to the southwest, by the Osterems to the northeast, and by the mouth of the river Ems to the south. The size of the area is about 88 km². The area was surveyed with 4 flights totalling to 414 line-km (110,238 survey points). The nominal separation of the 36 NW-SE lines and 11 NE-SW tie lines was 250 m and 500 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 five model layers).
