In the summer 2006 the University of Leicester and NGU will carry out a seismic tomography and Receiver Function field experiment experiment in the Central Caledonides from the Norwegian coast near Hitra to Sundsvall in Sweden.
35 Guralp 6TD seismometers (capable of recording signals of between 30 s period and 50Hz) has been secured from the UK Geophysical Equipment Facility (SEIS-UK) between March and October and will deployed in the study area. This will complement ongoing work by the University of Aarhus (Cenmove project), who carried out receiver functions experiments along two transects in Southern Norway . The transect provides constraints on crustal thickness, Vp/Vs ratio for the crust and the velocity structure of the upper mantle overcoming present short-comings in the knowledge of the deep crust of the Scandes mountain chain. Acquiring the new data allows a comparison between properties of the crust the topography and the uplift to be made and the cause of Neogene uplift and isostatic processes inferred.
