Large areas without oxygen called Dead zones emerged in the Baltic Sea during last century. They are major threat for life in the Baltic Sea. Main cause of their existence is eutrophication and stratification of water column. While eutrophication and outbreak of cyanobacteria deplete oxygen in deep waters, stratification prevents restoring original oxygen level. Project aims to reduce stratification of water column which would lead to oxygenation of deep waters and to elimination of the Dead zones. Proposed structures take advantage of deep water currents and redirect mass of water thus mixing stratified layers. Once these objects are formed by process of cyanobacteria sedimentation they are fully operational without any further action. No mechanical parts just pure formation of mass.

Structures would disturb status quo and create new conditions in complex water cycles with some unexpected side-effects. Problem of Dead zones is very complex problem that is difficult or impossible to solve because of missing data, constantly changing conditions or in this case deep connection with global environment. For those reasons is this project highly speculative. This provoking character of the project should ignite broader debate about problems of the Baltic Sea.
