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 October 1, 2020, OCEARCH tagged and released Nukumi, a 17 ft 2 in, 3,541 lb female white shark off Lunenburg, Nova Scotia. 🌊 She stands as one of the largest sharks studied by our team, and her data provides rare insight into the life of an adult female white shark. Her name honors the Mi’kmaq grandmother figure, symbolizing wisdom and teaching. Nukumi continues to shape shark science and inspire conservation, and her track is always available on the OCEARCH Global Shark Tracker at ocearch.o

White sharks Webster and Ripple, tagged and released in Mahone Bay during our expedition collaboration with the Tancook Islands Field Station, are already on the move south. In this week’s Tracking the Science update, Senior Data Scientist John Tyminski explains what their early migration tells us about white shark behavior in the Northwest Atlantic. Track Webster, Ripple, and other sharks in real time on the OCEARCH Global Shark Tracker App or at ocearch.org. | OCEARCH

Quint is a white shark being tracked on the OCEARCH Global Shark Tracker, and his movements are helping scientists unlock critical knowledge about shark behavior and ocean ecosystems. By studying where Quint travels, researchers can better understand migration routes, feeding grounds, and how apex predators like white sharks maintain the health of our seas. Each ping from his tag provides real-time data that advances shark conservation, informs global research, and protects the future of our oce

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
