The aim of the radar studies was to map the snow land ice layering along the traverse route, and to map basal conditions by sub glacial lakes and at sites chosen for detailed morphological analyses. The radar programme was carried out using three different radar systems. One CW-radar for high resolution snow depth recordings. The frequency band was 0.8-1.2 GHz. The other systems were mono pulse ... radars for the frequencies 60 and 179 MHz for studies of ice layering and basal conditions. The scientific programmes were linked to several international consortia and the entire project was part of the Trans-Antarctic Scientific Traverses Expeditions ? Ice Divide of East Antarctica (TASTE-IDEA). The scientific programmes were developed from the International Trans Antarctic Scientific Expeditions (ITASE), the Japanese deep ice core drilling programme Dome F (NIPR) and the European Project for Ice Coring in Antarctica (EPICA). We ran a 3000 km traverse between the Japanese station Syowa and the Swedish station Wasa, via the deep ice core drilling sites Dome Fuji and EPICA-DML. The route covered areas in both the Antarctic Southern Atlantic Ocean sector and the Antarctic Indian Ocean sector. The traverse was carried out during the austral summer 2007/08.
