Shark Bay stromatolites at risk from climate change

Oz Research of Note (in progress)

Climate change resulting in more frequent flooding of the Wooramel River that leads into Shark Bay is threatening the unique ‘living rock fossils’ that make Shark Bay a World Heritage site. These stromatolites – rocky structures formed over millennia by blue-green algae or cyanobacteria in which a new kind of chlorophyll has been found – thrive in Shark Bay’s Hamelin Pool, where an unusual undersea landscape has created an environment twice as saline as normal seawater.
