It is the main task of this workpackage to prepare the existing Icelandic infrastructures for more multidisciplinary observations and to integrate some observational facilities to the HOTSPOT infrastructure. This includes designing the HOTSPOT observatory station. The lead contractor, Reynir Bödvarsson, was the technical designer of the SIL system and is still active in its ongoing and further development. The assistant contractor Wolfgang R. Jacoby has a long-time experience in geophysical research in Iceland. He will start continuous gravity measurements in the Iceland highlands with existing gravimeters, which will be upgraded and prepared for continuous observations by Michel van Ruymbeke. Axel Björnsson, Andreas Junge and Martin Beblo have a long-time experience in observing conductivity in the crust by MT-method. They will integrate such measurements with available MT equipment in a continuous mode to the HOTSPOT infrastructure. All this will be carried out utilizing the experience and skill of the scientists and the technicians of the Icelandic Meteorological Office for the implementation.
