The primary aim of the work presented is to gain deeper understanding of the interaction between subglacial heat sources and ice, generally termed volcano-ice interaction. Common types of heat sources encountered are subglacial geothermal systems of different sizes as well as volcanoes or volcanic systems buried underneath glaciers or ice sheets. Previously reported sites featuring subglacial heat sources include several ice-filled calderas around the world (e.g. Clarke et al., 1989; Major and Newhall, 1989) and the large ice caps in Iceland, especially Vatnajökull and Mýrdalsjökull (e.g. Björnsson, 1988; Björnsson and Gudmundsson, 1993; Gudmundsson et al., 1997, 2002, 2004, 2007; Jarosch and Gudmundsson, 2007.) There is also evidence of an active volcanic area underneath the West Antarctic Ice Sheet, near the Whitmore mountains (Blankenship et al., 1993; Behrendt et al., 1994, 1995). Moreover, volcanic regions at high and middle latitude were ice covered during the Pleistocene and earlier glaciations (e.g. Velichko et al., 1997; Hickson, 2000).
