In the frame of glaciology and palaeoclimate research, Talos Dome (72°48lS; 159°06lE), an ice dome on the East
Antarctic plateau, represents the new selected site for a new deep ice core drilling. The increasing interest in this region
is due to the fact that the ice accumulation is higher here than in other domes in East Antarctica. A new deep
drilling in this site could give important information about the climate changes near the coast. Previous papers
showed that the dome summit is situated above a sloped bedrock. A new position on a relatively flat bedrock 5-6 km
far from here in the SE direction was defined as a possible new ice core site for an European (Italy, France, Swiss
and United Kingdom) drilling project named as TALDICE (TALos Dome Ice Core Project). This point, named as
ID1 (159°11l00mE; 72°49l40mS), became the centre of the Radio Echo Sounding (RES) flight plan during the 2003
Italian Antarctic expedition, with the aim of confirming the new drilling site choice. In this paper 2001 and 2003 RES
data sets have been used to draw a better resolution of ice thickness, bottom morphology and internal layering of a
restricted area around the dome. Based on the final results, point ID1 has been confirmed as the new coring site. Finally,
the preliminary operations about the installation of the summer ice core camp (TALDICE) at ID1 site carried
out during the XX Italian Antarctic expedition (November 2004-December 2005) are briefly described.
