Tagged great white shark Ripple covers 354 miles off Nova Scotia in a week
The subadult great white shark known as Ripple, tagged off Nova Scotia, traveled 354 miles in seven days, reaching a record distance for OCEARCH’s weekly tracking leaderboard.
A subadult great white shark identified as Ripple has been recorded traveling 354 miles in the past week, the longest distance logged for any shark in OCEARCH’s weekly rankings. The shark was tagged in September 2025 near the Tancook Islands, Nova Scotia, by the Tancook Islands Marine Field Station in partnership with the nonprofit OCEARCH. At the time of tagging, Ripple measured 11 feet 6 inches and weighed about 778 pounds.
Since its tagging, Ripple has moved along the Atlantic coast, covering more than 8,000 miles that include a southward passage past Florida and into the Gulf of Mexico before returning northward toward Canada. The latest satellite ping placed the shark roughly 45 miles off Cape Breton, Nova Scotia, marking the furthest north it has been observed by the organization.
OCEARCH noted that Ripple could either continue northeast toward Newfoundland or head northwest into the Gulf of St. Lawrence, an area known for supporting white-shark feeding activity. The organization added that great white sharks typically migrate north in the cooler months to seek food and return south in the fall and winter for warmer waters.
The nonprofit encourages the public to follow Ripple and more than 400 other tagged marine animals in real time via the free OCEARCH Global Shark Tracker app.
