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.

European institutions launch campaign for International Coccolithophore Day

Five European research institutions have announced an initiative to establish October 10 as International Coccolithophore Day, highlighting the crucial role of these microscopic plankton in regulating Earth's climate. Coccolithophores, tiny algae smaller than dust grains, capture carbon dioxide, produce oxygen, and form geological records of climate history. The campaign aims to raise awareness of their impact on ocean ecosystems amid climate change threats.
