Abstract : The influence of seawater carbon dioxide CO2 concentration on the size distribution of suspended particles 2?60 ?m and on phytoplankton abundance was investigated during a mesocosm experiment at the large scale facility LFS in Bergen, Norway, in the frame of the Pelagic Ecosystem CO2 Enrichment study PeECE II. In nine outdoor enclosures the partial pressure of CO2 in seawater was modified by an aeration system to simulate past ~190 ?atm CO2, present ~370 ?atm CO2 and future ~700 ?atm CO2 CO2 conditions in triplicates. Due to the initial addition of inorganic nutrients, phytoplankton blooms developed in all mesocosms and were monitored over a period of 19 days. Seawater samples were collected daily for analysing the abundance of suspended particles and phytoplankton with the Coulter Counter and with Flow Cytometry, respectively. During the bloom period, the abundance of small particles
