Marine Ecosystems

A trove of over 30,000 fossils unearthed on Spitsbergen reveals that ocean ecosystems rebounded swiftly following Earth's worst mass extinction. Just three million years after the event, complex food chains with large predatory reptiles thrived in ancient seas. The discovery challenges long-held views of a gradual recovery process.

New research from the University of St Andrews reveals that coastal upwelling regions are acidifying much more rapidly than previously thought. These areas, like the California Current, pull deep CO2-rich waters to the surface, intensifying the effects of atmospheric carbon dioxide. The findings raise concerns for marine ecosystems and fisheries worldwide.
