The observation and documentation of the seven seas is an integral part of our visual understanding. The water is represented in its most diverse characteristics. Aquasphere was created from the pilot's seat during the circumnavigation of the world in a single-engine sports plane. It documents the different perspectives on the world's oceans. Divided into seven columns according to the world's oceans, the four lines show the atmosphere with its water content, the horizon as the dividing line between the atmosphere and the sea, the sea as an appearance and as a surface. The Chenega glacier in Alaska is juxtaposed with this order as a representative of the cryosphere, which decisively determines the world's oceans.
