Holiday-bound beachgoers along the North Carolina coast are sharing the spotlight with some heavyweight visitors. Three satellite-tagged white sharks pinged off the state on Wednesday morning, registering hours apart between the Outer Banks and the Cape Fear region just as Memorial Day traffic begins ramping up.
Local coverage and tracker data identified the trio as Cross, Ripple and Bella. Cross, a roughly nine-foot juvenile, pinged near the North Carolina–Virginia border at about 7:10 a.m. Ripple was detected miles off the Wilmington area and is listed at about 11 feet and roughly 778 pounds. Bella, a near-10-foot juvenile, pinged in Raleigh Bay near the Ocracoke Inlet, according to CBS17.
Tagged In Canada, Tracked Down The Coast
Researchers say many of the tracked white sharks were sampled in Atlantic Canada last year, and recovered tag data helps scientists confirm size, sex and travel histories. OCEARCH's recent write-up on PSAT recoveries describes how popped tags and surface "pings" provide months of depth and temperature data that reveal migration patterns, according to OCEARCH.
Part Of A Wider East Coast Surge
Trackers and outlets have noted a flurry of detections from the Northeast down into the Gulf this spring, with multiple white sharks showing activity from New York waters to Florida. Meteorological and science outlets have highlighted the spike as sharks stage on the productive continental shelf off the Carolinas each year, which researchers say explains the uptick in pings, as reported by Fox Weather.
What Beachgoers Should Know
Experts stress that an offshore satellite ping does not mean a shark is patrolling the surfline and that unprovoked bites are rare. The International Shark Attack File advises common-sense precautions: swim near lifeguards, avoid dawn or dusk, stay away from fishing activity and calmly leave the water if you spot a shark, guidance found at the International Shark Attack File.
For scientists the pings are valuable research signals. OCEARCH senior data scientist John Tyminski wrote that "recovering a PSAT tag is a huge win for science," because archived tags reveal weeks or months of behavior beneath the surface. Researchers say that information will help explain why white sharks stage off the Carolinas and improve understanding of seasonal movements as ocean temperatures change, per OCEARCH.
