The Swedish team (blue line) started the route from the Swedish research station Wasa and the Japanese team (red line) started from Syowa, the Japanese research station. In late November 2007 four Japanese and four Swedish vehicles started out to meet on the Polar Plateau in late December for joint scientific efforts and exchange of crewmembers. The aim of the expedition has been to explore new scientific frontiers and to deepen our understanding of polar processes and their global linkages. The outdoor temperature is -33oC. It is 27 December and we are at 3 650 metre elevation (615 mb), 20 km from the meeting point for the two JASE field parties at 76oS, 26oE. We have not slept for two days and it will take many hours more until we have the chance of our eagerly awaited sleep. But right now we are thrilled and in just a few hours we will meet 18 FoRSKARRAPPoRTER CRUISE REPoRTS SWEDARP 2007/08 mEETIng POInT dOmE F syOWA our Japanese collaborators at the point we have strived so long to reach. Successful meeting The meeting was as joyful and satisfying as we had wished it to be. Both parties had travelled more than 1 500 km encountering a variety of difficulties along the way. The meeting was also the ultimate symbol marking the success of eight year’s of planning, the highly satisfying culmination of international collaboration, and, of course, the exceptional effort made by all expedition participants. Our journey to reach this point was much tougher than we had ever expected. We arrived at the Wasa station by airplane on 17 November
and the plan was scheduled to take off again at the same time as our departure on 29 November. However, due to harsh weather conditions and some technical failures our departure was delayed by five days and just a couple of days later we were trapped in another storm which consumed valuable time. In addition, we experienced technical problems with our vehicles, which forced us to drive far more slowly than originally planned. Nevertheless, many research programmes were run more or less as planned while we were struggling with our vehicles, and others were rescheduled for the drive back when we presumed we would have more time. After three days at the meeting point the Japanese field party took off for their return to Syowa station via Dome Fuji. Two of our scientists went with them and we were joined by two new expedition members, Hiroyuki Enomoto and Shin Sugiyama. present day studies We left the meeting point the day after New Years Eve and travelled along the ice divide Figure 3 An early morning start in -35°C.

One aim of our journey was to study the present day conditions along the flowline, conditions that are represented in a temporal mode in the deep ice core. We sampled snow chemistry and snow physics, snow layering, temperature and many other parameters. Our plan is to construct a synthetic ice core based on present day data aiming at excluding non-climatic signals from the ice core records. A number of radar systems were installed in and on the tracked vehicles. These radar systems were operated in different frequency ranges optimized for specific purposes such as bed mapping, ice- and snow layer mapping and snow surface scattering. Bed topography measurements are used primarily to complement knowledge about the Antarctic bed topography, but are also used for detailed studies of the physical settings of subglacial lakes. At present there are about 150 known subglacial lakes in Antarctica. The biggest of these is Lake Vostok, measuring 14 000 km2 Participants (cont.)
