The projects pursue a promising counter measure: Biorock technology, which was developed by German architect Wolf Hilbertz as early as the 1970s, and aims to accelerate coral growth and conserve marine biodiversity.
To this end, frames made out of steel and metal mesh, through which weak direct current flows, were sunk into the sea at Paynes Bay. Electrochemical processes initially lead to the formation of a crust on the surface made from certain salts dissolved in the sea water. Over time, a thick layer of solid limestone grows there. Real-time surveillance systems are used to permanently observe the water quality during the five-year monitoring programme.
The steel frames serve as artificial coral reefs – a great help for coral, as they don’t have to build their substrate themselves. Subsequently, living coral fragments that have broken off naturally, are transplanted onto the constructions. In direct collaboration with local researchers, it is ensured that the species of coral used can survive well at the site of the Biorock installation.
