deep space ocean 2019

In 55 years of manned space flight, 547 people have traveled through  space.

But only three people have seen the deepest parts of the ocean with their own eyes – 11.034 meters below sea level.


While star explosions in space led to the creation of all elements, making 

life on this planet possible, the oceans produce as much oxygen as all land plants together. They keep our bodies alive with every breath.


The oceans were always there, their surfaces still look the same like thousands of years ago.


"But if you look deeper, 90 percent of the oceans are overfished. Two thirds of coral reefs are badly damaged." (Sylvia Earle, oceanologist)


The video-sound-installation "Deep Space Ocean" wants to call attention to the depths.

My special thanks go to Professor Carolin Crawford of Cambridge University,

for her inspiration and especially the sounds she provided me with.


Your lecture on "Sounds of the Universe" is quite wonderful.
