World’s Largest Marine Tracking Project Maps Shocking Gaps in Ocean Protection for Whales, Sharks, and Turtles—Here’s What Needs to Change by 2030
Groundbreaking research tracks 12,000 ocean giants and exposes urgent need for new marine protection hot spots worldwide.
- 12,000+ whales, sharks, and turtles tracked via satellite
- 100+ marine megafauna species included
- 60% of critical habitats fall outside protected zones
- 50+ countries collaborated in this landmark effort
A revolutionary new study is rewriting everything we thought we knew about marine protection—and the lives of our planet’s greatest ocean nomads.
Led by Ana Sequeira of Australian National University and supported by the United Nations, a vast research team called MegaMove tracked more than 12,000 whales, sharks, turtles, and other marine giants. Their mission: pinpoint where these creatures are most vulnerable—and reveal exactly where current protections miss the mark.
Using state-of-the-art satellite tags and streaming data from over 100 species, nearly 400 scientists across 50 countries assembled the largest marine tracking dataset ever. The result? A stunning new blueprint for saving the world’s ocean giants.
Why Are Whales, Sharks, and Turtles at Risk?
Every year, giants of the sea migrate thousands of miles across invisible highways. But their ancient routes now collide with an ocean transformed by human threats—deadly fishing lines, busy shipping lanes, and pollution stretching horizon to horizon.
MegaMove’s findings, published in the journal Science, reveal how these animals’ patterns intersect with hazards. The tracking exposes flashpoints where marine life faces the greatest risk—areas where urgent changes could mean survival or extinction.
Q: Where Are These Threat Zones Located?
The biggest hotspots aren’t just in distant blue waters. The U.S. East Coast, including Virginia’s vibrant shoreline, sits right on a critical migratory corridor. These waters host apex predators whose presence helps balance entire ecosystems—a ripple effect that impacts fisheries, seagrass meadows, and even the fight against climate change.
Take Virginia, for instance. When predator numbers crash, it triggers collapses, like North Carolina’s shellfish fisheries and the decline of seagrass beds vital for carbon sequestration and coastline protection.
Q: What Is the 30×30 Ocean Protection Target—and Is It Enough?
The United Nations’ bold 30×30 goal aims to protect 30% of the world’s oceans by 2030. But MegaMove’s data-driven algorithms warn that drawing new boundaries isn’t enough. Even perfectly placed protected areas would still leave 60% of tracked animals’ critical habitats exposed.
How Can We Truly Save Ocean Giants?
Protecting more ocean areas is essential, but the research urges broader action:
- Redesign fishing practices to reduce bycatch
- Re-route shipping lanes away from key habitats
- Fight ocean pollution at the source
- Develop smarter, dynamic protection zones informed by real-time animal movement

Q: How Does Big Data Change Ocean Science?
Projects like MegaMove mark a revolution—uniting field biology with cutting-edge data science. Virginia Tech’s role in this international collaboration highlights a new scientific frontier, where students learn to decode massive biological data sets as readily as they tag animals in the field.
As marine ecologist Francesco Ferretti puts it, these global projects don’t just inform policy; they inspire future researchers and prove that local knowledge can drive worldwide change.
What Can You Do to Help Ocean Giants?
