An Iceberg flows gently on the Baldeneysee in Essen. From the explorers tent on top the sounds of nature sweap over the lake. The scientist on the perennial ice is searching for knowledge. Inside the Iceberg lies an unexpected and cool space, where the visitor can participate in this knowledge. 3 windows show visual transformations of sounds from the research studies in the Antarctic Ocean collected from the lab PALAOA of the Alfred-Wegener-Institute.
