IVL Swedish Environmental Research Institute is an independent, non-profit research institute,owned by a foundation jointly established by the Swedish Government and Swedish industry.IVL Swedish Environmental Research Institute was established in 1966 and has since then beeninvolved in the development of solutions to environmental problems, at national andinternational level.We work with applied research and contract assignments for an ecologically, economically, andsocially sustainable growth within business and society at large. The institute employs around 200experts, which makes IVL a leading institute for applied environmental research and consultancyservices.
CollaborationsWe are members of a number of national and international networks.We also have close collaboration with universities. Through these connections, we have access tounique knowledge and highly qualified partners.

Extent of oxygen-depleted bottom waterIn the Baltic Sea Worldwide
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 betterenvironment and opportunities for reproduction. Solved inorganic phosphorus released due to the reducing conditions in the bottomsediments will be bound in complexes and thus reduce the inorganic nutrientconcentrations 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!
WEBAP: How?The use of natural resources: Source of energy: waves Source of oxygen: oxygen-rich surface waterAdvantages: Oxygenation & mixing Simple and robust design with no moving parts No need for electricity
WEBAP: Planning and design18 tests with different wave conditions mooring forces Pump capacity for each wave spectra Stability Optimal ramp (30˚isoptimal) other details
WEBAP: Pilot IFacts 14 m with, variable ramp faces waves at all conditions outlet at 75m depthMeasurements Pump-capacity, wave parameter, currents,CTD-profiles, sediment, forces, stability, behaviour, etc.Operation period November 2010 to April 2013 (with interrupted operationbetween December 2010 to July 2011)
WEBAP: Pilot IIFacts 2,5 m in diameter, variable pump-capacity between 1-4m3/s maximal effect use 5 kW outlet at 100m depthMeasurements Pump capacity, CTD-profiles, sediments,metals, nutrients, currents etc.Operation period April 2011 to September 2012
WEBAP: Monitoring Online monitoring Field expeditions Water and sediment samples Historical data
WEBAP: Evaluation Data evaluation Modeling regional large scaleimpacts Laboratory testsEcotoxicology010203040506070O2 start O2 endMacomaMarenzelleriaMysis
Results (so far)? Measurements and mapping of the lack of oxygen in thearea indicate that the lack of oxygen in the pilot areas ismore widely spread than previously estimated Measurements confirm the estimatedpumping capacity at different wave heights Large scale implementation modelingestablishing that the technique does notaffect the salinity stratification Modeling for the Gotland Deep based onfield data show oxygenation of the wholearea down to the seafloor after only five years
Results (so far)? Tests with sediment and organisms from the pilotsites show no adverse effects of oxygenation Potential to bind up to 100 000 tones of phosphorus,which can be compared with the annual land supplyof around 30 000 tones /yr and the environmentalobjective to reduce this load by 15 000 tones /yr Several setups for different conditions (waves, etc.) Modeling of pumping in Kanholmsfjärden based onfield data shows effect of oxygenation not only inKanholmsfjärden but also in adjacent bays due to thehigh water exchange
Results (so far)? Lifecycle Assessment (LCA) and Lifecycle Cost (LCC)analyses indicates that the WEBAP is the most sustainableand cost-efficient alternative
