Scientists Confirm Critical Migratory Corridor Between Cocos Island and Osa Peninsula
In a major advancement for marine conservation, the One Ocean Worldwide Coalition (OOWC), in collaboration with Costa Rica’s National System of Conservation Areas ( SINAC ) and national park rangers, has successfully completed Phase 1 of a comprehensive scientific project that definitively maps a vital underwater migratory highway linking Cocos Island National Park with nursery and feeding habitats along the Osa Peninsula on Costa Rica’s southern Pacific coast. The study, conducted from March 2025 to March 2026 across Cocos Island, Isla del Caño, and coastal waters of the Osa Peninsula, used advanced non-invasive technologies including acoustic tagging, 30 BRUVS (baited remote underwater video stations) deployments, photo-identification, and genetic sampling. Preliminary results confirm the existence of a biologically critical Cocos–Osa Swimway that follows the underwater seamounts and ridges of the Cocos Ridge, connecting the remote oceanic sanctuary of Cocos Island with important m...
