Halvfarryggen
Halvfarryggen is a local ice dome in Antarctica. It lies about 100 km south-east of Neumayer III, the permanent German Antarctic research station, and defines the eastern boundary of the Ekströmisen catchement, the ice shelf on which Neumayer is located. Three ridges come together near the ice dome of Halvfarryggen. As it is located quite close to Neumayer it seemed a suitable site to test the new equipment. From airborne radar data it is known that upwarping internal layers exist, a so-called Raymond bump or isochrone arch. The special characteristics of the isochrones' geometry are an indication that anisotropies of the crystal orientation fabric (Martin et al., 2009) of ice might exist at Halvfarryggen. So it is a place where interesting glaciological features can be observed.
2010 field survey
During the Antarctic field trip in January/February 2010 ground-penetrating radar as well was seismic measurements were carried out on Halvfarryggen. The seismic line was shot on top of the dome with a length of 1455 m. The radar data were measured within a larger area on and around the dome, as well as a continuous measurement from the Neumayer station (green dot) to the Halvfarryggen dome and back.
Alpine field site Colle Gnifetti
The Colle Gnfetti is a glacier saddle in the Monte Rosa massif, Swiss Alps. With an altitude of 4450 m and an mean annual air temperature of about -14°C it resembles very well polar ice conditions. With easy access from Zermatt and the Capanna Margherita mountain hut near by it provides a great opportunity to test equipment nearby. Field surveys were carried out in 2008 and 2010 with radar and seimic equipment.
