Mapping of fracture zones using resistivity method between islands at Arsvågen, Bokn municipality, Rogaland - ROGFAST project

Abstract

This survey was carried out in cooperation with the Norwegian Public Roads Administration (Statens vegvesen) to aid and supplement the construction of a major tunnel in Arsvågen, Rogaland. Essentially, this work follows up ROGFAST project which also included resistivity measurements at the island of Kvitsøy just south of the new survey area. It is also in close connection to another NGU project which tested the efficiency of 2D resistivity method in marine environments. Our aim is to utilize the results of the aforementioned report in order to be able to discard the sea water effect and thereafter detect and characterize possible fracture sones which may affect the stability of the tunnel contruction at hand.
