Helicopter-borne Electromagnetics (HEM) Area 129 Esens
Description
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 Esens (2008/09) ranges from about Dornum and Aurich in the west to Wittmund and Werdum in the east. The size of the area is about 370 km². The area was surveyed with 23 flights totalling to 1542 line-km (437,562 survey points). The nominal separation of the 75 N-S lines and 8 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).
