![]() ![]() A classic two step inversion scheme is used where first maps of phase velocities at different periods are derived, and then a 1D transdimensional Bayesian method is applied to determine the VSV-depth structure. We present a new 3D shear-wave velocity model and Moho map of Scandinavia, which is based on the inversion of the merged phase dispersion curves from ambient noise and earthquake-generated Rayleigh waves. Most of the ocean floor in the North-Central Atlantic ocean south of the Charlie-Gibbs fracture zone follows the square-root-of-age prediction of the cooling half-space model (gray shading). For the NorthCentral Atlantic ocean the best-fit square-root-of-age dependence (as predicted by the cooling half-space model) is estimated for the ocean floor younger than 80 Ma. ![]() Anomalous bathymetry of the North Atlantic Ocean based on ETOPO1 data (NOAA, 2011) for bathymetry and ages of the oceanic crust based on a global compilation (Müller, 2002). without ice (ice thickness increases inland and reaches ca.
