A University of Ottawa-led team has pierced Greenland’s icy veil with unprecedented 3D temperature models of Earth’s subsurface, blending data from satellites, seismic readings and heat flow to map thermal quirks under the ice sheet and northeast Canada. PhD grad Parviz Ajourlou, first author, crunched hundreds of thousands of simulations on Digital Research Alliance of Canada supercomputers alongside Dutch colleagues from University of Twente and GEUS experts. The work spotlights stark lateral heat shifts revealing Greenland’s ancient sashay over the Iceland hotspot.
