Artistic exploration of the underwater soundscape of the Baltic Sea

On the 9th September 2016, the Kumu Art Museum in Tallinn opens the sound installation "Mare Balticum" based on a selection of sounds recorded during a scientific investigation conducted in 2014 and 2015 by BIAS: Baltic Sea Information on the Acoustic Soundscape. Collected from thirty eight hydrophones, these recordings were made at exactly the same time every hour, each day, for the whole year; this sonic map of the Baltic enables scientists to measure the effects of human-induced sound in the ocean.

In Mare Balticum, fragments of this comprehensive material have been merged in order to create a sonic portrait of the Baltic Sea. Spanning from the Bothnian Sea in the north to Öresund in the south, and from the Sea’s eastern reaches on the Estonian coast to its westernmost extents in the Danish archipelago, the work progresses temporally as well as spatially. In the installation, marine life, the forces of nature and the constant presence of the sounds of human activity converge. Read more about the installation here

Curator of the installation is Torun Ekstrand, who coordinated the South Baltic project Art Line. This artistic initiative brought together 14 arts and cultural institutions from Poland, Sweden, Germany, Lithuania and Russia. Art Line's recurring artistic theme was the Baltic Sea interpreted in series of artworks including "Telling the Baltic”, “Baltic Sounds Good”, the “Baltic Agora” and many others that have been shaping the Baltic cultural ambience. Art Line is conserving a plethora of cross-border artworks in a South Baltic cultural "treasure chest", available online at:
