2.3 Further activities
During August 1990, the Soviet nuclear icebreaker ’’Rossiya” (UPIG) carried a party of tourists
from Murmansk to the North Pole, cutting across the Eurasian Basin at longitudes 60°E and
95°E. As the vessel was not fully booked, we took the opportunity to join them and carry out
some research in co-operation with Hamburg University, Germany. The Arctic region is virtually
inaccessible to normal ocean-going vessels and, therefore, available ocean data is extremely
sparse. On the other hand, it is a region vulnerable to climatic changes. Closely spaced
temperature profile measurements in the upper 500 m of the water column were made using
T-7 (depth range up to 800 m) and T-5 (depth range up to 2000 m) XBTs dropped in leads or
small polynyas. Our assumption that XBT drops in ice-covered areas would be challenging was
confirmed, and only half of the 170 probes launched in the ice regime reached a depth of more
than 350 m. Nevertheless, the results obtained were well worth the effort. The data were
reported by Sy and Ulrich (1994), and the scientific results were published by Quadfasel et al.
(1991,1993).
Additional XBT measurements have been carried out occasionally by different German and
Russian research vessels in order to improve the data density of lines AX-1, AX-2 and AX-3.
An overview of all vessels which participated in the BSH SOOP from 1988 until 2002 is given in
