Back in 2019, a nonprofit marine research group tagged a great white shark off the coast of Nova Scotia. It wasn’t just any old shark, though — it was a shark that weighed nearly 1,000 pounds. And recently that shark, dubbed “Ironbound,” was spotted off the coast of North Carolina.
Ironbound, named after West Ironbound Island near Lunenburg, Nova Scotia, measures in at 12 feet, 4 inches long, according to OCEARCH, the research group responsible for the tracking tag. Ever since they first tagged him, the group has been tracking his movements in an effort to understand more about sharks’ migratory patterns. Every time a tagged shark’s fin breaks the surface, its location is shot over to OCEARCH, where it’s recorded and used to figure out how and where sharks move throughout the ocean.
