Abbildung 5.10. Der frische Westwind und die einsetzende Meeresströmung haben die 
10-15 cm starken Eismassen des Greifswalder Boddens in Bewegung 
gebracht. Innerhalb von wenigen Stunden türmte sich das Eis am 
Endhaken in Thiessow zu etwa 2 Meter hohen Eisbergen auf. Am Steilufer 
von Klein Zicker erreichten die Eisberge sogar über 3 Meter Höhe.

Figure 5.10. Fresh westerly winds and marine currents have set the 10-15 cm thick ice 
masses of Greifswalder Bodden in motion. Within a few hours, ice growlers pile 
up at the spit of Thiessow, reaching heights of up to 2 metres. At the bluff of 
Klein Zicker, the accumulations of ice reached heights of over 3 metres
