Several temporary seismological arrays have probed the crust and lithosphere in northern Germany and southern Scandinavia (Tor, CALAS, MAGNUS and TopoScandiaDeep, see e.g. Medhus et al., 2012). In 2011-12 we measured the Jutland-Lower Saxony (JULS) profile as collaboration between Aarhus University and GFZ Potsdam. This profile crosses the southern part of the Tor array in the North German Basin and goes all the way to the northern part of Jutland (mainland Denmark). First results are presented from this new study. P-traveltime residuals were modeled with a new flexible 3D tomographic method which maximizes resolution under profile arrays (Hejrani et al., 2011).
This optimized profile yields new information on the upper-mantle velocity field beneath Jutland and parts of northern Germany. It clearly outlines a high velocity body located in the uppermost mantle beneath the North German Basin. It correlates very well with the location of a similar body located by the Tor project (e.g. Gregersen et al, 2002, 2009). The northern part of the JULS model links well with the previous results from the CALAS and TopoScandiaDeep projects (Medhus et al., 2012).
