Japanese-Swedish Antarctic Expedition: On their way
Report no 6
Written December 5, 2007
We are on our way now with four tracked vehicles and five sledges. Our departure became delayed by a few extra days due to practical problems of various kinds. We started our traverse on December 4 and are now heading towards the Swedish station Svea. Some load adjustments will be carried out during the next few days to level the speed of the tracked vehicles. The plan is to drive to Svea and make some fuel arrangements and then go up Kibergdalen to the Polar plateau. Our science plan is unchanged but sample density and sample timing have by necessity been adjusted to the present situation.
Today we took a firn core close to the nunatak Fossilryggen and we also took snow samples for different projects. The weather ha...

Norway-US Traverse: A splendid day to drive across the horizon
Written December 3, 2007
3590 meters above sea level
With a sense of accomplishment, this noon we bid farewell to the packed snow and the lone temperature array transmitter, which is all that was left to mark our drilling site 91. Under a cool, cloudless sky, the horizon looked identical in all directions: flat and white, with lighter sky near the horizon fading into a deep blue straight up.
Very small patterns formed by drifted snow, less than ten centimeters high, now provide the major surface features. Such a huge expanse dominated by the smallest of features! The calm, clear, sunny day makes th...

Norwegian-US Traverse: Plane visit brings early Christmas
Written December 3, 2007
3587 meters above sea level
Minimum temperature: -47 °C
Clear, sunny skies today made it possible for a long-planned flight to visit us at site 91. We said good-bye to three of the part-time traverse crew, Tom, Unni, and Torbjørn, who are heading back to their jobs and families. They were a big help and also a joy to be with, and we will miss their company as we continue the traverse toward South Pole.
Today was also a special day, almost like Christmas, for our lead mechanic, Kjetil, who received six differentials for the vehicles! Two have broken so far on the traverse, and Kjetil has been able to replace them in the field. We are all hoping that now that we have plenty of extras, they will not be needed!

Norwegian-US EA Traverse: Narrowing the to-do list at Site 91
Written 2 December, 2007
3587 meters above sea level
Minimum temperature: -45 °C
Now that we have been here at Site 91 for three days, several of the main tasks here are done, and the list of things to do is becoming shorter. The big event yesterday was finishing the 90 meter ice core (well, 90.40 meters actually).
Drilling went so well that the core was finished almost a day early. Mary and Tom also finished the work in the snow pit by measuring the thermal conductivity and grain size, and collecting samples for stereology, stable isotope analyses, and trace chemistry. Atsu and Jan...

Norwegian-US EA Traverse: Drilling into fragile snow
Written December 1, 2007
3587 meters above sea level
Today was our second day here at Site 91, and we were again fortunate to have excellent weather to continue with our work. The drilling progressed nicely, reaching 59 meters by the end of the day, while Atsu coordinated the shallow drilling and recovered two more 7 meter cores.
At sites with very little snowfall (less than 10 cm of snowfall each year) and very low annual temperature (mean annual temperature ~ -50 °C) drilling can be a challenge, particularly in the upper 5 meters. Close to the surface, snow grains metamorphose from very...

Norwegian-US Traverse: Let's call this Site 91...
Written 29 November 2007
3587 meters above sea level
Thanks to the professionalism and dedication of Kjetil and Einar who worked throughout the night, Lasse?s differential gear was replaced and we were on our way to Site 91 by 9:10 am. But it happened again, this time to Chinook. Just as we passed the final 10 km mark to Site 91, she coughed out some weird noises and stopped running. The diagnosis, again, was differential gear failure.
As a result we were forced to stop and establish the camp around 4:00 pm. We are just 8.7 km short of the originally planned location, but where we are now became S...

Norwegian-US Traverse: First day at Site 91
Written November 30 2007
3587 meters above sea level
Site 91 is our first major science stop, and today was our first full day here. After a short meeting this morning, everyone picked up where they left off last night. The largest task at the major science stops (Sites 91, 92, 93, 94) is the ice core drilling. This morning, Lou, Stein, Glen and Tom finished setting up the Eclipse drill, and reached 31 meters depth by the end of the day; Atsu and Jan-Gunnar used a hand-powered drill to collect shallow cores; Karsten and Helgard worked on processing radar data and replacing some parts on their systems (and we hop...

Japanese-Swedish Antarctic expedition: Report #5
Written 28 November, 2007
3541 meters above sea level
Early Antarctic explorers may have had problems with their sled dogs, but we are now experiencing the problems of modern times — a broken-down traverse vehicle. Just as the day was coming to an end, with just one or two more hours of driving left, one of our four vehicles, Lasse, showed signs of a problem by means of a flashing red light on an instrument panel.
After a through inspection by our super mechanic Kjetil, it turns out that the differential gear (a gear that controls the speed of the wheels when making turns) needs replacing. The front part of Lasse is now covered with a tarp and heated so that maintenance work can be done in the cold of -45 degrees Celsius (air temperature at midni...
