Study warns offshore wind structures leach hazardous metals into marine environment

A new peer-reviewed study has warned that the rapid expansion of offshore wind farms could be releasing significant quantities of hazardous metals into marine ecosystems, with potential long-term consequences for seabed health and marine species.

The research, published in Marine Pollution Bulletin and conducted by scientists from Bangor University, Imperial College London, and other institutions, examined how materials used in offshore wind infrastructure – including antifouling coatings, galvanic anodes, and corrosion protection systems – leach metals such as copper, zinc, and aluminium into surrounding waters.

The paper notes: “Metals such as copper and zinc are well known for their toxicity to marine invertebrates and fish, with sublethal effects occurring at concentrations only slightly above background.” The authors warn that the expansion of offshore wind without fully accounting for these emissions could pose “a significant chemical pressure on marine ecosystems”.

But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

  • I was a "conspiracy theorist". Now I'm just right.

Not the hill to die on, IMHO. Every vessel out there does much the same. Zinc has long been used to provide 'sacrifice' metals and ward off corrosion in more vital parts, and copper sheathing was used to thwart shipworms and other biota buildup or damage to wooden hulls, even when the ships were powered by sail (or even slaves with oars)..

Structures from bridges to buoys all will have similar metallic signatures.

Seventeen Techniques for Truth Suppression

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.

When we would go into Hong Kong, local contractors would come along side with long handle roller brushes and paint over the accumulated rust for several days.  That was how we handled the problem. 000hehehehe
