A groundbreaking study published in Nature Communications highlights the critical role of coralline algal beds in the global carbon cycle. Researchers have found that these unique marine habitats act as significant carbon sinks, storing large amounts of calcium carbonate and contributing to the mitigation of climate change.
Coralline algae, which form extensive beds on ocean floors, produce and store calcium carbonate (CaCO₃) over millennia. However, the study also shows that increasing ocean acidification poses a threat to these habitats, accelerating the dissolution of the carbonate deposits.
The research team, led by CCMAR marine scientists, measured the net primary productivity and carbonate production in coralline algal beds across the Atlantic and Mediterranean. Their findings revealed that these ecosystems are not only key players in long-term carbon storage but also influence short-term carbon fluxes based on environmental factors such as light exposure.
These insights are crucial for understanding the role of marine ecosystems in mitigating climate change, as well as the potential risks posed by ocean acidification to these natural carbon sinks.
