In a major advance for marine conservation, WWF and a global coalition of leading scientists, civil society, governments, and tech innovators have launched BlueCorridors.org—a dynamic new platform that brings together three decades of whale tracking data with information on overlapping marine threats and conservation solutions. For the first time, the migratory “blue corridors” used by great whales are now digitally mapped and made publicly accessible to inform science, policy, and ocean protection efforts worldwide.
