Helicopter-borne Electromagnetics (HEM) Area 128 Langeoog

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 Langeoog (2008/09) comprises the island of Langeoog, the western portion of the island of Spiekeroog, the Wadden Sea to the south of the islands as well as an onshore stripe ranging from about Dornum in the west to Werdum in the east. The size of the area is about 259 km². The area was surveyed with 12 flights totalling to 1080 line-km (314,672 survey points). The nominal separation of the 68 N-S lines and 7 W-E 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).
