AB  - We studied how exposure to oil spill response technologies affect marine 
      microorganisms during Arctic winter and spring. Microorganisms were exposed to 
      chemically dispersed oil (DISP), in situ burnt oil (ISB), and natural attenuated 
      oil (NATT) in mesocosms from February to May. We subsampled the mesocosms and 
      studied the effects of oil in laboratory incubations as changes in biomass of the 
      major functional groups: bacteria, heterotrophic-nanoflagellates, 
      dinoflagellates, ciliates, pico- and nanophytoplankton, and diatoms over two 
      14-day periods. In winter, the majority of polycyclic aromatic hydrocarbons 
      (PAHs) remained encapsulated in the ice, and the low concentrations of PAHs in 
      water led to minute changes in biomass of the investigated groups. In spring, 
      however, when the PAHs were partially released from the melting ice, the biomass 
      of many functional groups in DISP and NATT decreased significantly, while the 
      changes in ISB were less pronounced. The overall biomass reduction, as observed 
      in this study, could lead to a disrupted transfer of energy from the primary 
      producers to the higher trophic levels in oil affected areas.
