The Gulf of Mexico has a way of keeping its secrets just beneath the surface. Sometimes those secrets surface briefly — not with a fin slice or a splash — but with a satellite ping.
That was the case when “Ripple”, a sub-adult male great white shark, appeared off the Louisiana coast near New Orleans, drawing national attention and reopening an old Gulf debate about how often white sharks really pass through these waters.
According to FOX Weather, Ripple was tagged by OCEARCH on September 30, 2023, off Mahone Bay, Nova Scotia. Measuring roughly 11 feet long and weighing close to 778 pounds at the time of tagging, Ripple began a southbound migration typical of North Atlantic white sharks. What wasn’t typical was where that migration eventually led. By winter, his satellite tag pinged from the northern Gulf of Mexico — just offshore of New Orleans — placing him squarely in waters many still consider outside the great white’s normal range.
But Ripple wasn’t alone.
According to OCEARCH tracking data, the year 2024 revealed a broader and more revealing pattern of great white shark movement in the Gulf. Several other OCEARCH-tagged white sharks — Keiji, Crystal, and Rose — also entered waters south of New Orleans, confirming that Ripple’s appearance was part of something larger.
Keiji, a male great white also tagged in Nova Scotia, surprised researchers when he pinged near the New Orleans area in late March and again in April. According to OCEARCH, this timing stood out because male great whites typically begin a steady northward migration by early spring. Keiji’s continued presence suggested that the Gulf is not just a winter stopover, but a flexible and recurring part of his range.
Rose followed a similar path. According to OCEARCH, her April pings in the region further challenged long-held assumptions about rigid white shark migration schedules, highlighting how dynamic and adaptable these predators can be.
Crystal’s visit was perhaps the most striking. According to OCEARCH, this large female great white entered the waters south of New Orleans in January 2024, marking one of the westernmost movements ever recorded for an OCEARCH-tracked white shark. Her presence reinforced the idea that even mature females are willing to push deeper into the Gulf than once documented.
While satellite tracking has only recently confirmed these movements, the Gulf has been telling this story for decades.
According to our Gulf Great White Sightings Database , credible reports of great white sharks in or near Louisiana waters date back to at least the early 1980s. One of the most notable accounts occurred in 1982, when offshore workers reported a large great white shark swimming beneath the lights of an oil platform in Louisiana waters — its size and unmistakable shape clearly visible in the glow.
Additional sightings followed. According to our Gulf Great Whites Sightings Database, a 14- to 15-foot great white was reported near an offshore rig close to Sabine Pass in 2005, and anglers later reported white shark encounters near the Louisiana–Mississippi border around 2010. These reports, once dismissed as anomalies, now closely mirror the routes revealed by modern satellite tags.
Taken together, Ripple’s presence near New Orleans, the confirmed movements of Keiji, Crystal, and Rose, and decades of documented sightings tell a consistent story: the Gulf of Mexico has long been part of the great white shark’s world.
What has changed isn’t the sharks behavior — it’s our ability to follow them and their response to enhanced conservation efforts.
According to OCEARCH and reinforced by historical data archived by Gulf Great Whites, great white sharks are not rare wanderers in the Gulf. They are seasonal visitors, explorers, and participants in a complex ecosystem that scientists are only now beginning to fully understand.
