![]() ![]() “The shallow coastal areas and sandbanks combined with stable wind resources make the North Sea an ideal area for renewable energy production and have made the North Sea a global hotspot for offshore wind energy production,” their paper states. The paper explains that the North Sea is a shallow shelf sea system, in which “the interactions between bathymetry, tides and a strong freshwater supply at the continental coast foster a complex frontal system, which separates well-mixed coastal waters from seasonally stratified deeper areas”. ![]() They say that their results “provide evidence that the ongoing offshore wind farm developments can have a substantial impact on the structuring of coastal marine ecosystems on basin scales”. Their model also projects an increase in sediment carbon in deeper areas of the southern North Sea due to reduced current velocities, and decreased dissolved oxygen inside an area with already low oxygen concentration. Increased sedimentation could occur not only at the offshore wind farm clusters, but may also distribute over a wider region, the scientists say in a paper published in scientific journal, Communications Earth and Environment. They forecast sedimentation could increase by as much as ten per cent as a result of transforming wind into electrical power. The scientists from the Helmholtz-Zentrum Hereon Research Institute used numerical modelling to show how there could be physical disruptions to the marine environment, along with sedimentation and wind flow from turbines. A team of German scientists has suggested that offshore wind farms in the North Sea could significantly impact the ecosystem. ![]()
