A massive adult male great white shark (Carcharodon carcharias) has shown up multiple times in recent weeks off the North and South Carolina coasts.

Breton
The shark is known as Breton. Breton’s name was chosen by Sea World, in conjunction with OCEARCH, a global nonprofit organization that studies and works to preserve these apex predators.
Breton was tagged by OCEARCH on September 12, 2020, off the coast of Scatarie Island, Nova Scotia. This male was the first shark to be tagged during OCEARCH’s Expedition Nova Scotia 2020. The shark’s name was chosen in honor of the people of Cape Breton where it was tagged.

At his tagging, Breton was already a giant, measuring 13 feet 3 inches and weighing 1,437 pounds. Today, nearly two and a half years later, the shark is almost certainly over 1,500 pounds.
Recording Breton’s Data
OCEARCH records ping data to track the sharks that it tags. In order for a ping to be geolocated, the tagged shark must break the surface of the water and cruise at the surface for a minimum of 90 seconds. That allows OCEARCH to record three pings which are required to pinpoint the shark’s precise location.
The organization also records Z-pings, which occur when a shark swims to the water’s surface but doesn’t remain there long enough for the three pings that would reveal its specific location.
The Coast of the Carolinas
Breton’s latest pings reveal that he is swimming off the coast of the Carolinas. On January 25, 2023, OCEARCH recorded multiple pings for Breton close to the coast of Myrtle Beach, South Carolina.

Then, they received pings the next two days, January 26 and 27. This time, Breton was off the coast of Bald Head Island, North Carolina.
Even more recently, OCEARCH received a Z-ping from Breton’s transmitter. The Z-ping was received on February 16, 2023. While it didn’t provide his location, that Z-ping does tell us that Breton is still surfacing off the U.S. Atlantic coast.
The sharks that OCEARCH don’t always show this kind of ping activity. Sometimes weeks or even months go by with no data received from a shark’s tag. We don’t know what had Breton so active near the water’s surface of the Carolinas recently, but he has certainly provided researchers with a lot of data. Apparently, he is quite a fan of the Carolina coastal waters. But that doesn’t mean he never goes anywhere else. Quite the contrary.
Breton’s Travels
Since his initial tagging, Breton has been a prolific traveler up and down the eastern seaboard of Canada and the United States.
Breton’s northernmost ping was in the Honguedo Strait off Quebec’s Anticosti Island coast. His most southern ping was off the Turks and Caicos Islands south of the Bahamas.
All told, Breton has covered a whopping 26,114 miles of Atlantic water since his tagging in September 2020. And, given recent data, he’s not slowing down anytime soon.
