Clusters of Excellence 80 (EXC): The Future Ocean, Ocean Acidification - Foraminiferal shell loss in the Flensburg Fjord (SW Baltic Sea). Living benthic communities under the risk due to acidification?

Description: Foraminifera dwelling in the Baltic Sea are especially sensitive to ocean acidification due to the low carbonate saturation levels. An enhanced shell loss in living benthic foraminifera was observed in Flensburg Fjord during summer 2006. This project aims (1) to better constrain the factors influencing carbonate saturation and foraminiferal shell loss and (2) to establish the reaction of the foraminifer Ammonia beccarii to different pCO2 in seawater. For these purposes seasonal changes in pH, total alkalinity (TA) and foraminiferal communities will be monitored over the year 2009. We also will culture A. beccarii in order to determine their calcification rates under different pCO2, and to establish the critical thresholds for calcification and growth.
