[Coral-List] Mineral Accretion/ Biorock

Hi Daisy,

So I’m stepping in here because of the public forum and my role with the IUCN Coral Specialist Group. The reason the scientific literature ends in the 1970s is that success, in spite of many applications since then, has been very limited. Speaking from the perspective of the potential ‘beneficiary’ locations and countries, while clearly mineral accretion sounds great, it has not been shown to have persistent effects, on a scale that matters, to the reef, nor to people.

The field of reef restoration is advancing rapidly now (and we desperately need it to) and the most recent aggregation of knowledge/technology comes through the Coral Restoration Consortium and the Reef Futures conference of December 2018 (see links below).
But we don’t have a truly independent review/assessment of the pros and cons of different restoration techniques, and its important to think of any particular technology, such as mineral accretion, in the context of other options (perhaps done jointly), and the broader context of pressures and resilience/recovery factors.

This doesn’t mean the technology won’t in the future, and perhaps what it needs is hard core R&D from a commercial company like yours partnering with the scientists trialling it. But expect it to be 10 years (ie. this is not a short-term kick for the company) before you can really demonstrate significant step changes from what has been reported so far, in order to be sure you’re really promoting success, rather than just advertising solar power!! Its so important not to advertise research as ‘development’ until you can demonstrate success and benefits, in the peer-review literature. Prematurely putting it on a glossy brochure advertising the CSR benefits of offshore solar before doing that will continue the confusion over what restoration works and what doesn’t, and who benefits.

So … please do look into it and by all means further the research with a critical eye.

all best,
