Dear MARMAM, We are delighted to announce the launch of BlueCorridors.org https://bluecorridors.org/, a groundbreaking digital platform that marks a significant advance for marine conservation. Blue corridors are the migratory "superhighways" used by great whales, connecting them to vital breeding, feeding, and social habitats across ocean basins. These routes are essential not only for whale survival but also for the overall health of marine ecosystems. For the first time, these critical blue corridors are digitally mapped and made publicly accessible, providing valuable information for science, policy, and global ocean protection efforts. The platform transforms decades of scientific research into a practical tool for action, showing "when, where, and how to protect whales in a rapidly changing ocean". This initiative is a collaborative effort by WWF (https://wwfwhales.org/), technology partner Ode (https://ode.partners/en) and a global group of scientists and organisations (https://bluecorridors.org/collaborators) The site features ca. 1,437 tracks for 8 whale species, collected over 31 years by more than 50 data contributors. The platform offers a powerful, interactive tool that combines migration data with layers of marine threats and conservation priorities to guide protection efforts across national borders and various disciplines. Key features include: * Whale movement maps by species and time of year, which can be produced and shared. * Conservation data from partners like the IUCN Marine Mammal Taskforce’s Important Marine Mammal Areas (IMMAs) and other ecologically important zones, informing future marine protected area design and planning. * Overlapping threats, including shipping routes, fishing effort, and climate change layers. * Case studies, highlighting hotspots where whales are most vulnerable and outlining actionable solutions for governments. BlueCorridors.org builds on the collaborative "Protecting Blue Corridors" report (https://wwfwhales.org/resources/protecting-blue-corridors-report) and meets a growing need for open-access, science-based marine conservation tools. It visualises the growing risks to whales and outlines marine conservation solutions to inform policy. We encourage you to explore the platform at https://bluecorridors.org<https://bluecorridors.org/> and discover how this innovative tool can support your work. Importantly, this is only the first step for BlueCorridors.org – for example, we would like to add additional tracking data (including data for other species). Watch out for updates in the year and sign up to stay connected!
