Recent studies show that scientists were right about the fact that marine life thrives near offshore structures of wind farms. Two groups of seals were tracked by marine biologists at two different wind farms. One pack regularly visited a farm in Alpha Ventus that lies off the German coast whereas the other pack was seen frequenting Sheringham Shoal at the south-eastern coast of England.

Many small fish and crustaceans are found around the surface of the sea and close to the giant columns that stretch to the ocean floor. The team of scientists found that almost 11 seals are active within Sheringham Shoal and Alpha Ventus.

The movements of seals were tracked by using GPS technology and it was noticed that they moved from one turbine to another looking for prey in such areas.

Marine biologists recorded the grid pattern of a track that is made by an offshore wind farm in Norfolk. Researcher Deborah Russell from the University of St. Andrews in Scotland was amazed to see that the seal moved in between the turbines looking for prey and stopped at certain spots where it found abundant food.

"You could see that the individual appeared to travel in straight lines between turbines, as if he was checking them out for potential prey and then stopping to forage at certain ones", said Russell.

There are numerous farms along the coasts in Europe as the farmers there use environmental friendly energy as a better solution for electricity. But in the US, there is resistance for establishing such farms as the homeowners along the coast wish to retain the view.

Wind farms sit on the ocean floor due to which artificial reefs are caused that attract crustaceans and other invertebrates. This lures both gray seals and harbour seals to come to this area for food. Marine biologists keep carrying out their research on these structures to find out how they will affect the environment.
