Baltic Sea Ice Climate Workshop 2005 
18 
Fifth (September 2005): Hamburg, Germany 
The fifth workshop was held in the University of Hamburg. The organiser was Dr. Corinna 
Schrum. Participants came altogether 23 (Fig. 2): 2 from Estonia, 3 from Finland, 8 from 
Germany, 1 from Poland and 3 from Sweden, and additionally from outside the Baltic Sea there 
were 2 participants from Canada, 1 from France and 2 from Norway. The presentations filled 
two and a half days, with oral and poster sessions included. 
The Baltic Sea ice climate was strongly present in the workshop, but a changing was clearly 
seen toward a “Baltic Sea ice science workshop”, dealing with many different types of ice 
problems. Also there were invited talks representing other seas of the seasonal sea ice zone, 
namely Bohai Sea in China, a freezing sea at 37^tO°N (closest to the Equator for an annually 
freezing sea), and Arctic shelves. The proceedings of the workshop are presently in 
preparation, with Dr. Corinna Schrum as the editor. 
Final remarks 
Baltic Sea Ice Climate Workshops have been organized since 1993 at three-year intervals, the 
first one in Tvarminne, Finland and the fifth in 2005 in Hamburg (Fig. 3). It has been a very 
enjoyable and fruitful series, with significant openings into the sea ice research of the Baltic 
Sea. In particular, as results have come the following: IDA data bank for ice model calibration 
and validation has been set up, joint modelling studies have been performed, and ice time 
series have been jointly analysed. Also the topics discussed in the workshops have spread 
from geophysics into neighbouring disciplines, in particular sea ice ecology. The proceedings 
books of these workshops have come to a major literature source of the Baltic Sea ice 
research.
