the Baltic Sea area testing in ideal conditions. A large-scale spill may be impacted by wave dynamics, ice and snow, and cold and warm conditions. Here sophisticated modelling work will better predict the possible impacts and spreading velocities. The behaviour of chemical spills in winter conditions should also be studied more thoroughly, and recommendations should be given for appropriate countermeasures. ■ HÄNNINEN & RYTKÖNEN: Oil transportation and terminal development in the Gulf of Finland.
