Jahrgang 83 | Nr. 89 
Mittwoch, den 21.04.2010 
vier Tagen von Südskandinavien E- bis NE-wärts 
verlagert, bestimmt. In der Bottenvik werden 
windbedingte Anderungen der Eislage vorherrschen: 
Das Eis auf See wird in den nächsten zwei Tagen in 
S-liche, danach in E- bis SE-liche Richtungen 
treiben. Im Finnischen und Rigaischen Meerbusen 
sowie in der Bottensee wird sich der jahreszeitliche 
Eisrückgang relativ schnell fortsetzen. 
Scandinavia eastwards to northeastwards during 
the next three to four days. In the Bay of Bothnia 
wind-induced changes of ice situation will 
dominate: The ice at sea will drift southwards within 
the next two days, thereafter, towards east to 
southeast. The seasonal ice retreat in the Gulfs of 
Finland and Riga as well as in the Sea of Bothnia 
will continue rather rapidly.
