The drill hit bedrock in about 4 weeks. The retrieved core was 346 m long. In this project only minor amounts of cargo and people had to be transported, thus the little Twin Otter airplane was perfectly suited for the operation. The Hans Tausen project 1995 Working in the field requires team spirit and good cooperation between all the participants. The dayly work might be hard and sometimes awkward, but the time in the camp is usually accompanied by many a good laughter and establishment of new friendships.
Field work is hard.
A picture of the climatic conditions and the variability during thousands of years can be obtained through various measurements of many parameters by different methods. However, discovering indication of i.e. abrupt temperature changes in the ice at a certain depth is of no use at all, if one does not know the age of the specific ice. So dating the ice is absolutely essential. Ice for chemical analysis has to be cleaned very carefully. This is done in a laminar flow bench, where it is also cut into 5 cm segments, ready to be melted in the clean room laboratory in Copenhagen and analysed by ion chromatography.
