Offshore wind farms are projected to impact primary production and bottom water deoxygenation in the North Sea

open access: yesCommunications Earth & Environment, 2022
The wind wake effect of offshore wind farms affects the hydrodynamical conditions in the ocean, which has been hypothesized to impact marine primary production. So far only little is known about the ecosystem response to wind wakes under the premisses of
