Abstract
Encouraged by the success and experience gained during the Polarstern expedition ARK-IVl3, in surnrner 1987, discussions and preparations of a rnulti-disciplinary expedition into the central Arctic Ocean focussing On oceanography and geosciences started early. At the Same time Swedish scientists began planning of a similar multidisciplinary but independent expedition with their new ice breaker Oden to the high Arctic, which was CO-ordinatedby the Swedish Polar Secretariat. Early contacts of the Swedish Polar Secretariat, the Alfred Wegener Institute and scientists involved, soon led to the decision to combine the two efforts. Soon after 1989, US scientists joined the discussions and introduced a third vessel to the joint venture, the US Coast Guard ice breaker Polar Star. Consequently, Polarstern ARK-VIIIl3 and ODEN'91 becarne part of a larger international expedition: The International Arctic Ocean Expedition ARCTIC'91. Strong efforts were rnade during the whole planning phase to include a Soviet participation; not only to invite a larger group of Soviet scientists but to have a Soviet ice breaker joining the international effort.
