Fate and effects of oil spills and oil remediation actions in sea ice- biodegradation
In collaboration with 18 international institutes, the Norwegian Polar institute will take part in a large-scale field experiment investigating fate and effects of oil spills and oil remediation actions in the Arctic sea ice ecosystem. The project consists of three work packages and is led by Akvaplan-Niva. Large mesocosms will be frozen into the Svalbard sea ice during five months, covering the period from icing to melting and from darkness to the return of light. Research conducted by the Norwegian Polar Institute will involve measuring microbial degradation of oil under true Arctic conditions, and investigating effects of oil and oil remediation actions on ice associated bacterial community structure and function. Combined with the detection of physico-chemical oil weathering, microbial biodegradation constitutes one work package, where research will be performed in close collaboration with Cedre (France), IRIS and Akvaplan-Niva (Norway).
