Corals Make Light Work of Photosynthesis Despite Lack of Sunshine
New Curtin University research has found reef-building corals living deep underwater off the coast of Western Australia’s Kimberley region survive despite a lack of sunlight by kicking into ‘photosynthesis overdrive’ to enhance their ability to gain energy from sunlight and by upping their intake of microorganisms.The study was done at Ashmore Reef Marine Park and focused on largely unexplored deepwater mesophotic coral, which live between about 30m and 150m deep, a zone where the limited amount of light is challenging for corals, which obtain most of their energy from the sun.

Heatwaves Decimate Sea Urchins, Molluscs - Study
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.Lead author Adjunct Professor Fred Wells, from Curtin’s School of Molecular and Life Sciences, said the west end of Rottnest Island had suffered a “catastrophic decline” in biodiversity. “Since 1982, we have monitored biodiversity of marine molluscs and echinoderms including sea snails, clams, starfish and
AI Set to Tackle Jetty and Port Corrosion Across WA
A team of researchers led by Curtin University have joined forces to develop an artificial intelligence tool to improve the maintenance of marine structures such as jetties and ports impacted by corrosion.The joint project, led by the Curtin Corrosion Center, has received funding from SmartCrete CRC to deploy the new monitoring tool and to look at better ways to repair ageing marine structures built with commonly used engineering materials such as reinforced concrete.Lead researcher Dr Mobin Salasi, from the Curtin Corrosion Center, said marine structures commonly corrode due to their exposure to
Reseach Finds Fin Whale Songs Shed Light on Migration Patterns
A Curtin University-led research team has uncovered valuable information on the migration patterns of the fin whale, as well as where they breed and feed, which will help aid in the monitoring and protection of the species.Published in Frontiers in Marine Science, the research team monitored 285,000 hours of underwater sound recordings from 15 locations off Antarctica and Australia between 2002 and 2019 and identified two migratory pathways used by the species – from the Indian sector of Antarctica to the west coast of Australia and from the Pacific sector of Antarctica to the east coast of

past.“There is still much to learn about mass extinction events and studying these disruptive time intervals further will inform us more about the history of our Earth, but also what climatic changes we can expect moving forward as CO2 levels continue to increase.”This research, led by Curtin University and funded by the ARC, was conducted in collaboration with researchers at the University of Southampton, Lahmont-Doherty Earth Observatory, MIT, and Oxford University. Dr Fox did the research as part of his PhD studies at Curtin and is now at Khalifa University.The full research paper, &lsquo
