Biodegradation of crude oil in Arctic subsurface water from the Disko Bay (Greenland) is limited
Biological degradation is the main process for oil degradation in a subsurface oil plume. There is, however, little information on the biodegradation potential of Arctic, marine subsurface environments. We therefore investigated oil biodegradation in microcosms at 2 °C containing Arctic subsurface s...

Biological degradation is the main process for oil degradation in a subsurface oil plume.
