SEA LEVEL AND THE CARBONATE SAND FACTORY IN SOUTH AUSTRALIA

Posted 12 March 2017

"Stable parts of the South Australia coast show that the last interglacial sea level was 2m higher than present, but elsewhere there has been relative subsidence up to 7m and uplift of 18 m. Estimates of changing sea level, and future projections, should state the time period involved and the tectonic background to be of any use. The coast contains ‘carbonate sand factories’ where organisms produce vast amounts of sand by fixing carbon dioxide as carbonates. Far from dissolving carbonate by acidification, carbon dioxide is an essential part of carbonate production and the continued maintenance and growth of coasts and reefs. Government policies to adapt renewable energy are unlikely to affect the system."  A new paper by Professor Cliff Ollier, of Australia.
