Melting ice strengthens southern ocean carbon barrier
Freshwater from melting ice and increased precipitation is temporarily trapping carbon dioxide in the deep Southern Ocean, countering predictions of a weakening carbon sink. Scientists from the Alfred Wegener Institute explain this stabilizing effect in a new study. However, intensifying winds may soon reverse this protection, potentially releasing stored CO2 into the atmosphere.

Reported by AI
A swirling supercomplex that captures ocean light for photosynthesis was detailed in a scientific publication on September 11, 2025. This discovery enhances understanding of marine algal energy processes. It was featured in the latest issue of a prominent science magazine.
Deep-sea mining poses new threat to sharks and rays
A new study warns that proposed deep-sea mining could endanger 30 species of sharks, rays, and chimaeras whose habitats overlap with mining zones. Nearly two-thirds of these species are already threatened with extinction from human impacts. Researchers from the University of Hawai'i at Mānoa highlight risks from seafloor disruptions and sediment plumes.
