Researchers in Australia are utilizing various mollusk shells as natural archives to reconstruct historical climate and environmental data.

In Southeast Queensland, a study led by the University of Queensland demonstrated that snail shells can act as environmental proxies. By using radiocarbon dating and the VEGA Accelerator, researchers found that growth spurts in snail shells correspond to severe weather events, such as cyclones or extreme rainfall.

Similarly, in the northern Great Barrier Reef, scientists analyzed the geochemistry of giant clam shells to reconstruct month-by-month climate conditions at the Lizard Island Group over approximately 200 years. This analysis revealed that prior to industrial-era warming, summers in the region were cooler than current temperatures, while winter conditions remained relatively consistent.
