Revealing the Arctic Crust

A new model, ArcCRUST, reveals with unprecedent resolution the geometry and the thermal state of the oceanic crust of the High Arctic and Circum-Arctic domain.

The Artic and Circum Arctic domain remains a poorly-explored regions of the Earth. Lebedeva-Ivanova et al. [2019] present—for the first time—a complete picture of the crustal layers for the Arctic and subarctic region adopting a consistent and coherent approach, based on gravimetric data and seismic refraction. The model sheds light on the crustal structure of the area and has been made openly available to researchers worldwide. The model reveals the structure of the crustal layers and of the sedimentary basins with unprecedent resolution. Those data provide the fundaments to reconstruct the tectonic and geodynamic history of this region.
