Science Expedition in Norway’s Deep-Sea Mining Frontier

In summer 2025, the Greenpeace ship Witness ventured into the Norwegian Sea’s newly designated deep‑sea mining zones. Onboard scientists executed combined visual and acoustic surveys, documenting cetacean species—including sperm whales and northern bottlenose whales—in areas slated for mineral extraction. Their findings underscore the critical role these seafloor ecosystems play for whales, highlighting the threat posed by industrial noise, sediment plumes, and seabed disturbance, and reinforcing Greenpeace’s call for a moratorium on deep‑sea mining pending further environmental assessment.
