The distribution of geothermal flux in West Antarctica ...
The West Antarctic Ice Sheet (WAIS) contains the equivalent of ∼3.3 m of global sea level rise and is the largest ice sheet on Earth grounded almost entirely below sea level. This is a potentially unstable configuration that makes WAIS prone to rapid collapse during interglacial periods, a condition...

The West Antarctic Ice Sheet (WAIS) contains the equivalent of ∼3.3 m of global sea level rise and is the largest ice sheet on Earth grounded almost entirely below sea level. This is a potentially unstable configuration that makes WAIS prone to rapid collapse during interglacial periods, a condition known as marine instability. One poorly understood but possibly dominant process in past and future collapses of WAIS is its coupling with the underlying West Antarctic Rift System (WARS), a Jurassic through Cenozoic region of intracontinental extension characterized by active volcanism. WARS’ topographic range, complex tectonic history, and volcanism exert a large influence on the distribution of elevated geothermal flux, a critical but poorly constrained ice sheet boundary condition for the collapse-prone marine- based WAIS.
