Percy is a white shark being tracked on the OCEARCH Global Shark Tracker. Each time his tag pings, scientists gain new insights into shark migration, behavior, and the role these apex predators play in keeping the ocean balanced. By following Percy’s movements, researchers can better understand the habitats white sharks rely on and the importance of protecting those ecosystems. His journey adds to the growing body of open-source data that drives shark conservation and helps secure a healthier fu

Hey OCEARCH Crew! 🌊 Ever wondered how our Global Shark Tracker works — or why sometimes it looks like a shark swims across land? Each shark carries a SPOT tag that connects to the Argos satellite system, but they only ping when they come to the surface. That means there can be gaps in time and space between pings. If those pings are near a peninsula or coastline, the Tracker draws a straight line between them — even if it cuts across land. We don’t “guess” the route — we show you the real data.

On September 30, 2020, OCEARCH tags Mahone, a male white shark measuring 13 ft 7 in and weighing 1,701 lbs, off the coast of Lunenburg, Nova Scotia. At tagging, Mahone is a sub-adult shark, representing an important stage in the growth and development of this iconic species. Mahone continues to provide critical open-source data that helps scientists understand white shark migrations, habitat use, and the role of these apex predators in maintaining ocean balance. His track is always available on

Before every expedition day begins, the OCEARCH crew puts in hours of preparation to make sure the team is ready for safe and successful shark research. In this update, Chris Fischer explains the critical role weather plays in planning and how Brett and DJ’s precision ensures the crew has the best chance at productive fishing and science workups. From monitoring conditions to fine-tuning the vessel’s readiness, this behind-the-scenes look shows how much work happens before the first line even hi
