Antarctica is a pivotal component of the global climatic system however it remains the least known continent on Earth from a geological view point. Geothermal heat flow depends on several geological factors including mantle heat flux, heat production of the crust, and tectonic history. The heat flux underneath the ice in Antarctica is fundamentally important because it influences the basal melting of the ice and thereby defines the boundary condition for ice sheet behaviour, subglacial hydrology, and sea-level change.
In addition, the heat flux helps provide an insight into the subglacial geology. However, recent assessments of the large-scale heat flux underneath the Antarctic continent have shown significant differences, and this parameter is very poorly understood.
REVEAL aimed to explore the interaction of subglacial geology and ice behaviour across the entire Antarctic continent and it provided an improved knowledge of the geothermal heat flux and its fundamental impact for several scientific communities, including glaciology and the solid Earth sciences. In addition, our potential fields and tectonic models and interpretations enabled the REVEAL researcher to test several hypotheses regarding the effects of tectonic collision, accretion and rifting on the continent as well as improving understanding of the impact of supercontinental assembly and break up on Antarctica.
