![]() This natural-color satellite image was acquired on March 26, 2010, by the MODIS aboard NASA’s Terra satellite. The eruption is located at the Fimmvörduháls Pass between the Eyjafjallajö kull ice field to the west (left) and the Mýrdalsjö kull ice field to the east (right). March 31, 2010.The volcanic eruption near Eyjafjallajö kull persists into its second week, with continued lava fountaining and lava flows spilling into nearby canyons. Till macrofabric was measured close to theĮruption of Eyjafjallajö kull Volcano, Iceland Flutes and crevasse-fill ridges were found superimposed on drumlins in places. The forefield of Múlajö kull mainly consist of subglacial landforms (drumlins, flutes and crevasse-fill ridges), end moraines and sandur plains. During the field work numerous radial crevasses, supraglacial channels and moulins were observed in the marginal zone of Múlajö kull. The area of abundant infiltrated water was distinguished close to the ice margin in the radarogramm obtained on Þjórsárjö kull suggesting successive supraglacial meltwater infiltration towards glacier margin. ![]() Also feature of subglacial topography that resembles drumlin was identified. In one of the obtained radarogramms possible subglacial channel below Múlajö kull glacier was identified. In obtained radarogramms it was possible to trace reflections from the glacier bed till depth of approximately 144 m as well as numerous prominent reflections from internal meltwater channels of glacier. GPR signals propagation speed in glacier ice was determined using reflections from internal meltwater channels of glacier. In total approximately 3 km of GPR profiles were recorded. During data acquisition 2000 ns time window was used, while length of profiles was determined using GPS device Garmin GPS-76. ![]() GPR measurements were performed on both outlet glaciers using 38 MHz and 75 MHz antenna systems. In the research ground penetrating radar (GPR) Zond 12-e was used. This work describes preliminary results obtained during the expedition to Múlajö kull and Þjórsárjö kull glaciers in August, 2014. The forefield of Múlajö kull comprises the active drumlin field of more than 110 drumlins (Johnson et al., 2010 Jónsson et al., 2014) and therefore is an excellent area for studies of glacial geomorphology, subglacial topography and ice structures. Múlajö kull and Þjórsárjö kull are surge-type outlet glaciers of the Hofsjö kull ice cap, central Iceland (Björnsson et al., 2003). KaruÅ¡s, JÄnis Lamsters, Kristaps BÄ›rziņš, DÄvids The geomorphology and ground penetrating radar survey results of the Múlajö kull and Þjórsárjö kull surge-type glaciers, central Iceland The contrasting surge characteristics could be explained by differences in glacier geometry, topography and substratum of the Drangajö kull and Vatnajö kull surge-type glaciers. Our results indicate that (a) greatest surface thinning in the upper reservoir areas of Drangajö kull rather than proximal to the equilibrium line during Vatnajö kull surges and (b) development of Drangajö kull surges that resembles Svalbard surge-type glaciers rather than Vatnajö kull surge-type glaciers. This surface thickening along with considerable ablation of the receiving areas will most likely return the glacier surface profiles to the pre-surge stage. Despite a negative geodetic net mass balance derived from the digital elevation models, the reservoir areas have been gaining mass since the surge terminations. ![]() The surface draw-down in the reservoir areas was usually 10-30 m during the surges, while the thickening of the receiving areas was significantly more variable, on the order of 10-120 m. The observations show a distinct ice discharge, most of which was from the upper reservoir areas, down to the receiving areas during the surges. Annual glacier-frontal measurements were used to estimate average ice velocities during the last surge of the glaciers. Surface elevation and volume changes of the Drangajö kull surge-type glaciers, Reykjarfjarðarjö kull and Leirufjarðarjö kull, were studied by comparing digital elevation models that pre-date and post-date their most recent surges.
