Divers are attempting to regrow Great Barrier Reef with electricity

A trial is underway to restore damaged coral on the Great Barrier Reef using electricity.
The reef has been severely assaulted in recent years by cyclones and back-to-back heatwaves.
Nathan Cook at conservation group Reef Ecologic and his colleagues are attempting to regrow surviving coral fragments on steel frames. The frames are placed on damaged parts of the reef and stimulated with electricity to accelerate the coral’s growth (see video).
Electrified metal frames have previously been used to encourage coral growth on reefs in South-East Asia, the Caribbean and the Indian Ocean. They have been shown to attract mineral deposits that help corals grow 3 to 4 times faster than normal.
