Eutrophication has many effects algae blooming phosphorous-depending cyanobacteria dead bottoms and hydrogen sulphide
Ecological and biological problems, large future economic problems for tourist- and fishery industry in the Baltic region.
(1) Nitrogen is emitted to waters
(2) Spring blooming of plankton
(3) Algae die
(4) Algae are de-composed which consumes oxygen
(5) Bottoms get anoxic
(6) Phosphorous is released
(7) Summer blooming of cyanobacteria

Need for action? Doesn’t the Baltic take care of itself? How affects and is the Baltic affected by climate change? Can technical solutions help in a long term?
Why do we think we need actions also in the Baltic and not only at sources? There sure is a good monitoring of sources and these sources can be abated? The Baltic in imbalance? Weakening of natural processes? Restore the Baltic Sea self-
cleaning biogeochemical processes?

WEBAP: AimImproved oxygen situation in deep water layers Species that are dependent on conditions in deep water, would get a better
environment and opportunities for reproduction. Solved inorganic phosphorus released due to the reducing conditions in the bottom
sediments will be bound in complexes and thus reduce the inorganic nutrient concentrations in the water.
Yet: 2-6 million tons of oxygen needed each year! Enormous amounts of energy to pump oxygen down to 80-120m depth!
Mission impossible?!

WEBAP: How?The use of natural resources: Source of energy: waves Source of oxygen: oxygen-rich surface water
Advantages: Oxygenation & mixing Simple and robust design with no moving parts No need for electricity

Results Measurements and mapping of the lack of oxygen in the
area indicate that the lack of oxygen in the pilot areas is more widely spread than previously estimated
Measurements confirm the estimated pumping capacity at different wave heights
Large scale implementation modeling establishing that the technique does not affect the salinity stratification
Modeling for the Gotland Deep based on field data show oxygenation of the whole area down to the seafloor after only five years

More results Tests with sediment and organisms from the pilot
sites show no adverse effects of oxygenation Potential to bind up to 100 000 tones of phosphorus,
which can be compared with the annual land supply of around 30 000 tones /yr and the environmental objective to reduce this load by 15 000 tones /yr
Several setups for different conditions (waves, etc.) Modeling of pumping in Kanholmsfjärden based on
field data shows effect of oxygenation not only in Kanholmsfjärden but also in adjacent bays due to the high water exchange
