Australian Scientist Maps Ocean Havens for 100+ Species

For the first time, scientists know exactly where the ocean's most magnificent creatures go to feed, breed, and migrate, and the discovery couldn't come at a better time.

Associate Professor Ana Sequeira from The Australian National University has been named Australia's National Champion in the Frontiers Planet Prize, one of 25 scientists worldwide competing for recognition in the world's largest science competition focused on planetary health. Her research brought together nearly 400 scientists to track more than 100 species of marine megafauna using satellite data.

The study, published in Science, combined tracking information for whales, sharks, sea turtles, and seabirds to create the first comprehensive map of where these animals spend their time. The findings reveal something crucial: many of the most important ocean habitats fall outside existing protected areas.

"We now have a clear, science-based roadmap capable of changing the trajectory of global marine biodiversity conservation," Sequeira said. The research identifies shared hotspots where multiple species gather, offering practical guidance on where ocean protections could help the most animals at once.

The timing matters tremendously. One third of these marine species currently face extinction, yet they play essential roles in keeping our oceans healthy. Healthy oceans, in turn, support life on Earth by regulating climate, producing oxygen, and feeding billions of people.

The Ripple Effect

The research arrives just as major international ocean agreements take effect. The findings provide evidence to guide implementation of the High Seas Treaty and Australia's newly passed High Seas Act, both designed to protect waters beyond national borders.

The work also contributed to a new international policy report developed with the United Nations University Centre for Policy Research. The report recommends expanding marine protected areas, integrating key habitats into national ocean planning, and strengthening protections for migratory species that cross international boundaries.

Sequeira now advances to compete for one of three international champion prizes worth $1 million each. The funding would allow her to scale up the research and reach more policymakers worldwide.

The recognition highlights how large scale collaboration can solve problems too big for any single country. By pooling tracking data from researchers across continents, the team created a resource that benefits everyone working to protect ocean life.

For marine conservationists who have long worked with incomplete information, having a global map of critical habitats represents a powerful new tool for their efforts.
