Although multidisciplinary observations in Iceland, in the very active area above the center of the Hotspot are extremely significant, it is also necessary to study the plume over a larger area to cover its dimensions.
Seismic observations from the surrounding areas, Scandinavia, Great Britain and Greenland, will also be integrated into the HOTSPOT infrastructure with the important aim to add data for seismic tomography of the plume. The networks in these areas will be supported to make their observations more easily accessible for research. The participation in the project will also give a boost for necessary extension of these networks. The most significant future extension is to initiate ocean bottom observatories in the area between Scandinavia, Greenland, Great Britain and Iceland.
