Crust-mantle transition and Moho model for Iceland and surroundings from seismic, topography, and gravity data

The regionalized regression results are used to construct a new Moho depth map from the gridded topography file. It compares reasonably to other recent maps. A notable feature is a band of crustal thickening along the SE Iceland shelf edge continuing northward across eastern Iceland to the Jan Mayen Ridge. This and other features suggest an evolution of the North Atlantic where a continental edge splinter carried into eastern and perhaps northern parts of Iceland, beside the Jan Mayen Ridge.
